WAGNER Wieland - luni-solar phase (5)

 Wieland WAGNER

January 5 1917 - 9h15 (AM) - Bayreuth, Germany, 49n57, 11e35 - Timezone : MET h1e
source : [https://www.astro.com/astro-databank/Wagner,_Wieland]

German opera director.
Wieland was the elder of two sons of Siegfried and Winifred Wagner, grandson of composer Richard Wagner, and great-grandson of composer Franz Liszt through Wieland's paternal grandmother.
Wieland Wagner is credited as an initiator of Regietheater through ushering in a new modern style to Wagnerian opera as a stage director and designer, substituting a symbolic for a naturalist staging and focusing on the psychology of the drama. [https://en.wikipedia.org/wiki/Wieland_Wagner]

recall : the aspects between planets and ASC are plotted directly in OA and those between planets and MC are indicated directly in AR. The aspects between planets are indicated in mundo (for the actual domification, i.e. Regio).


ZODIACAL – MUNDANE

In our research, we hypothesised that the mundane chart alone should be considered; also we must base on the aspects taken in the semiarcs the research of the degrees likely to be considered in the duration of the life.
In the case of Wagner, Wieland we have the table above which allows us to estimate the breakdown of aspects between the different planets and the alchocoden.
When considering a theme, the first thing is to observe whether it is diurnal or nocturnal. In the case of Wagner, Wieland, it is DIURNAL.
In this case, the first point to check is SU. If  SU is well disposed, it can claim 1st stage to be HYLEG.

SU is P and therefore seems weak, with a dignity score of [-10],
But, when we look for the dignities that appear in the zodiacal inscription of ASC, we find none.
we find at least one aspect to match with the dignities
We'll see later what we get when we search for mundane dignities.
Now that we know that we cannot consider SU as hyleg, we are left with MO but we don't find any aspect to match with the dignities,,,

Now that we doubt to take MO as hyleg, we are left with the choice of ASC and that of POF. It is the way in which is laid out MO which will indicate the choice to us. If MO is waxing, we take ASC for hyleg ; if MO is waning, we take POF for hyleg,
It turns out that MO is waxing; so we will take ASC,

Now we must look for the alchocoden: it is the planet which has the maximum dignity with regard to the hyleg and which exchanges a Ptolemaic aspect with the hyleg.
if we consider the MUNDANE system, we observe an opposition aspect of SA.
At the same time, it appears that SA has  dignity of TRI over ASC.
So we have two possibilities with our hypothesis : first choose ASC for hyleg ; second choose the MUNDANE system and try to find another couple of hyleg/alchocoden,
If we choose now ASC we must know that no trad authority agree with this choice
In case of ASC is the Hyleg, there is then two candidates to be alchocoden:  and 
First, we have to see which candidate has the most dignity: here, ME has candidate alcho dignities referring to ASC : [TERM and FAC] : weak dignities
SA is linked with ASC by an [opposition] aspect and a [TRI + RUL] dignity,
However, SA is [D] and has a power of [-19], and so SA has a bad Kadkhudah score of [7]
SA is located at 118,15° at more than 5° from [Δ degrees cups sup [VI] : 27,28° (150)] and has a domitude Regio of : [177,28] for a latitude of [0,18°]
Ultimately, ASC can be considered HYL, and SA as ALCHO.

Wieland Wagner, who was a heavy smoker, died of lung cancer on October 17, 1966.

important note: the SA and DM of the two points are always counted as daytime if the first point A1 (promissor) is above the horizon, even if the second is below. They are all counted as nighttime if the first point A1 (promissor) is below the horizon, regardless of the position of the second point A2 (significator). In present case SA et DA are all quoted N (see Choisnard, 'Langage Astral, p, 152, Ed, Trad,, 1963

DIRECTION : CMO conj SA    17 10 1966                
---------------------------------                    
We must take into account an important element: the ascensional difference (DA); it can be observed on the  graph in a dotted line (measured between the horizon and the axis of the pole). This is the difference between Right Ascension (AR) and Oblique Ascension (OA). This is the difference between Right Ascension (AR) and Oblique Ascension (OA). DA is always calculated in absolute value |DA| and it is added or subtracted from 90° (SA = 90° corresponds to a point on the equator cut by the horizon; depending on whether a star approaches or moves away from the line of horizon, SA is > 90° or < 90°, i,e, (+) depending on whether it is diurnal and northern ; or nocturnal and southern ; (-) depending on whether it is diurnal and southern ; or nocturnal and northern. But we have to take care of a fact : when we have a countra parallel or an aspect, the quadrant is not the same and the declination is different ; so the sign is also different.                    
                    
sin(DA) = -tan(φ)tan(δ)                    
φ = latitude 49,95 N                    
δ SA = 20,72 +                    
DA-SA = 26,74°                     
δ CMO =25,44 +                    
DA-CMO =34,47°                     
                    
We will first use the Placidus system of mundane directions. The simplest system is that of Choisnard-Fomalhaut. First you need to retrieve the data from the SA (semi-arc) and the DM (meridian distance) of the nocturnal point because the altitude of SA is -1,43°. important note: the SA and DM of the two points are always counted diurnal if the first point (here SA) is above the horizon even if the second is below. They are counted nightly if the first point (SA) is below the horizon regardless of the position of the second point.                    
For DMs, they are counted in AR from the diurnal meridian if the fixed point SA is diurnal, and from the nocturnal meridian if it is nocturnal.                    
                    
nocturnal meridian MC = 59,72°                    
AR SA = 120,29°                    
AR CMO = 69,6°                    
                    
 = 55,53°                    
DM N  CMO = 9,89°                     9,89°
                    
For the  significator  CMO altitude (h) =-14,1°. so :                9    
                    
 = 63,26°                    
DM N  SA = 9,89°                    
            2        
Then we compute Saf/DMf (so : SA f [ 55,53°] / DM f [ 9,89°])                    
                    
Sa f / DM f =5,61                    
                    
and the angle x = SAm x DM f/SA f, so : SA m [ 63,26°] x DM f [ 9,89°]/SA f [ 55,53°]                    
                    
 x = 11,27°                    
                    
We find the direction by DMm - x, so : DM m [ 9,89°] ± x [11,27]                    
We must now have regard to the double ± sign of the last expression; in the case where f (SA) and m (CMO) are on either side of the meridian, the direction arc is obtained by taking the sum (instead of the difference) of the two quantities DMm and x. This is not the case here, so sign = (+)                    
the computation of the arc requires, depending on the case, a reduction of 360° (so arc modulo 360°)                    
---------------------------------                    
arc D =49,3°                    
---------------------------------                    
in the technical sense, It is a direct direction but in the astrological sense, it is a true converse direction since it is an aspect considered as a promissor which goes towards the significator. ; so the m point is an aspect (here CMO) and the f point is a planet or an axis, (here SA)                    
                    
We can now compute the converse direction : point f is directed towards point m, i.e. the star is directed towards the aspect. This is where the problem of the orientation of the primum mobile arises because it is not concevable to rotate the local sphere in both directions… It does not seem convenient to postulate that the arc of direction is counted in the order of the signs of the zodiac (when it is direct, i.e. when one directs a promissor towards a significator): indeed, the ecliptic has nothing to do with a direction since this one depends only on the diurnal movement ( primum mobile). It is therefore otherwise that we must pass judgment on this.                    
                    
That time, we compute Sa m / DM m (so : SA m [116,74] / DM m [119,43])                    
                    
Sa m / DM m =1,04                    
                    
and the angle x = SA f x DM m/SA m, so : SA f [ 55,53°] x DM m [119,43] / SA m [116,74]                    
                    
x = 53,17°                    
                    
We find the direction by DM f - x, so : DM f [ 9,89°] ± x [53,17°]                    
We must now have regard to the double ± sign of the last expression; in the case where m (CMO) and f (SA) are on either side of the meridian, the direction arc is obtained by taking the sum (instead of the difference) of the two quantities DM f and x. This is not the case here, so sign = (-)                    
---------------------------------                    
arc C =43,28°                    
---------------------------------

REGIOMONTANUS

We must first determine the respective ascensional differences under the pole (DAP). The ascensional difference (DA) is the difference between right ascension and oblique ascension. The difficulty in calculating oblique ascensions lies in determining the correct ± sign to use; the following table makes it easier to navigate and allows for the adjustment of the values ​​found in the subsequent table: it provides the adjusted oblique ascension values ​​required to calculate primary directions according to the Regiomontanus method.

Thus, we see that the significant points lie in the DO zone (3)—corresponding to the third sector situated between DS and FC—which is a zone of oblique descent rather than ascent. The ± sign is determined by the declination of the significant point, resulting in two formulas: DO = AR + DA if the declination is + (N), or DO = AR - DA if the declination is - (S).

Now we can study the same direction with the Regiomontanus system. To obtain the arc of direction between two signifying points (planets in body, aspect versus planet, planet versus axis) one must find AO (oblique ascent) of f and of m, calculated under the pole of f.
The formulas to use can be found either in the ‘Dictionnaire astrologique’ of Henri Joseph Gouchon (Dervy Livres, 1937) pp. 266-267, or in his ‘Horoscope annuel simplifié’ (Dervy, 1973) p.181. Other formulas can be found in ‘Les moyens de pronostic en astrologie’, Max Duval (editions traditionnelles, 1986) and ‘Domification et transits’ (Editions traditionnelles, 1985). We can also cite by André Boudineau : ‘Les bases scientifiques de l’astrologie’ (Chacornac, 1937) These are references in French but there are many other references in English or German of a less obvious but equally valid use.

First, compute the ascensional difference under f (SA) : cot DAP f = (cot de f x cot lat) / in DM f ± cot DM f, i,e, :  cot (DAP f) = (Cot dec f[20,72°] x Cot Lat [49,95°]) /sin DM f [60,57°] ± cot DM f  [60,57°]

DAPf = 17,79°

We find the pole of f (SA) by formula : tan(pole f) = sin (DAP f) x cot (dec f) i,e, tan(pole f) = tan f [26,71°] x cot f [20,72°]

pole SA regio  =49,92°

(1) We need now the DAP of m (CMO) under the pole of f, sin (DAP m) = tan (pole f) x tan (DEC m), i,e, : (SA) : sin (DAPm/f) = tan [49,92°] x tan [25,44°]

DAP m/f = 34,42°

then we find for the points located in the eastern part of the chart : AO f = AR f± DAP f ; sign (+) if Dec f boreal or sign (–) if Dec f Austral ; so : AO f SA = 147° and AO m = AR m ± DAP m ; idem for sign ; so  AO mCMO = 104,03°

---------------------------------
arc D Regio = 42,97°
---------------------------------
We are now going to compute the converse Regiomontanus direction corresponding to the arc  f SA / p CMO

First, compute the ascensional difference under m (CMO) : cot DAPm = (cot dec m x cot lat)/sin DM m ± cot DM m, i,e, :  Cot(DAP m) = (Cot decm[25,44°] x Cot Lat [49,95°]) / Sin DM f [9,89°] ± Cot DM m [9,89°]

DAP m = 3,57°

We find the pole of m (CMO) by formula : Tan(pole m) = Sin (DAP m) x Cot (dec m) i,e, Tan(pole m) = Sin m [12,39°] x Cot m [25,44°]

pole CMO regio  =24,28°

We need now the DAP of f (SA) under the pole of m, Sin (DAP f) = Tan (pole m) x Tan (DEC f), i,e, : (CMO) : Sin (DAP f/m) = Tan[24,28°] x Tan [20,72°]

DAP f/m = 9,82°

then we find for the points located in the eastern part of the chart : AO m = AR m ± DAP m ; sign (+) if Dec m boreal or sign (–) if Dec m Austral ; so : AO m CMO = 82° and AO f = AR f ± DAP f ; idem for sign ; so  AO f SA = 130,11°

---------------------------------
arc C Regio = 48,12°
---------------------------------
H.J. Gouchon [l’Horoscope Annuel simplifié, Dervy, 1973, p, 181-182 and Dictionnaire astrologique, p, 277, 1937-1942, Gouchon ed., 1975, Dervy, but be careful because in DAP's equation, the double sign ± was mistakenly replaced by the sign (-) ] advises to avoid errors, to always place the star A1 (for us f, i.e. SU) in the eastern houses; in fact it is enough to change the registration number of the house based on the transformation (IV-V-VI) -> (X-XI-XII) and (VII-VIII-IX) -> (I-II-III ) to adapt the double sign ± in the calculation of DAP f or DAP m; moreover, this sign must be reversed if |DM| > 90°.

For the Regiomontanus directions, there is another mode of computing, mentioned by Gouchon (Dictionnaire astrologique, op. cit., p. 276) and especially Martin Gansten (Primary directions, pp. 155-157, the Wessex Astrologer, 2009) - This is the method of Henri Selva (La domification, Vigot, 1917, reprint Lacour 1992)
It consists at computing first 3 auxiliary angles before  the pole. It then joins the other method. Contrary to what Gouchon says, I find it easier than the previous one because we avoid the double sign ± in the determination of DAP f.

So, initially, we have A => Tan f = tan dec f [20,72°] / cos DM f [60,57°]

A = 37,59°

Then : B = Lat [49,95°] + A [37,59°]

B = 87,54°

And, Tang C = Cot DM f [60,57°] x Cos B [87,54°] / Cos A [37,59°]

C = -1,75°

Then, we have Sin pole f = Cos C [-1,75°] x  Sin LG [49,95°]
---------------------------------
So, pole SA regio = 49,92°
---------------------------------
Now go back to (1)

For m CMO; we have : A => Tan m = tan dec m [25,44°] / cos DM m [9,89°]

A = 25,77°

Then : B = Lat [49,95°] + A [25,77°]

B = 75,72°

And, Tang C = Cot DM m [-189,89°] x Cos B [75,72°] / Cos A [25,77°]

C = 57,52°

Then, we have Sin pole m = Cos C [57,52°] x  Sin LG [49,95°]
---------------------------------
So, pole CMO regio = 24,27°
---------------------------------
Now go back to (1) and see also the Regiomontanus table.

II. Luni- solar phase 

This is a method that we find outlined in Vettius Valens [book VI 9] as indicated by Anthony Louis in his blog :              
 'Vettius Valens had a different notion of annual returns. He felt that the return of the Sun each year was insufficient for forecasting for the year ahead because it omitted the influence of the the Sun’s partner, the Moon. As a result, Valens used a hybrid chart for the annual return which consisted of the positions of the planets when the Sun returned to its natal position each year but these positions were placed in a chart whose Ascendant and houses were determined by the moment the Moon returned to its natal degree during the zodiacal month when the Sun was in its birth sign.' [The Tithi Pravesh and its Monthly and Daily Iterations, November 5, 2022]              
Placidus uses it in his Primum mobile (Tabulae primi mobilis cum thesibus et canonibus 1657) and gives the procedure to follow in the XL canon (De Progressionibus, p. 53). A complete example appears in the analysis of the theme of Charles V (Exemplum Primum Caroli V. Austriaci Imperatoris, pp. 59-62).              
There is only one site on the internet that does this calculation:  https://horoscopes.astro-seek.com/calculate-planet-revolutions-returns/            
            
but it only gives the soli-lunar return at D0; Placidus continues the progression until end of process (i.e. even). For example in the case of Wagner, Wieland, if we take the date of 17 Oct 1966, we must first translate this date into 'life-year equivalent': we find :            
---------------------------------------            
EVEN    49,7820364521361    49    Y
0    9,38443742563351    9    M
    11,5331227690052    11    D
    12,7949464561252    12    H
        47,7    M
---------------------------------------            
The method of “embolismic lunations” as a predictive technique :   See : Tabulae Primi Mobilis,,, Placido De Titis, Patavii, MDCLVII             
An embolismic lunation, correctly termed an embolismic month, is an intercalary month, inserted in some calendars, such as the Jewish, when the 11-days' annual excess over twelve lunar months adds up to 30. An arbitrary application of this was used by Placidus, who applied the term Embolismic Lunation, to a Figure cast for the moment of the Moon's return to the same relation to the Sun that it occupied at birth. It was made the basis for judgment concerning the affairs and conditions of the ensuing year of life.' [https://astrologysoftware.com/community/learn/dictionary/lunation.html]               
The solar year does not have a whole number of lunar months (it is about 365/29.5 = 12.37 lunations), so a lunisolar calendar must have a variable number of months in a year. Regular years have 12 months, but embolismic years insert a 13th "intercalary" or "leap" month or "embolismic" month every second or third year [...]. Whether to insert an intercalary month in a given year may be determined using regular cycles such as the 19-year Metonic cycle [...] or using calculations of lunar phases [...]. [wikipedia]               
The whole difficulty therefore comes from the fact that there is no overlap between the solar month (30 D) and the lunar month (synodic month 29.53), consequently between the solar year (365.242) and the lunar year (354.367).             
 'In Vedic timekeeping, a tithi is a "duration of two faces of moon that is observed from earth", known as milа̄lyа̄ [...] in Nepal Bhasa, or the time it takes for the longitudinal angle between the Moon and the Sun to increase by 12°. In other words, a tithi is a time duration between the consecutive epochs that correspond to when the longitudinal angle between the Sun and the Moon is an integer multiple of 12°. Tithis begin at varying times of day and vary in duration approximately from 19 to 26 hours. Every day of a lunar month is called tithi.' [wikipedia]              
We see that the interest of Placidus' method (outlined by Vettius Valens) comes from the fact that the individualisation structure of the progression system is no longer represented by a single point (solar return or lunar return) but by a distance ( in this case the distance between SU radix and MO radix).            
We find in the literature another method which is similar to that of the solilunar phase: it is the tertiary directions. We find a critique of it in “Les Moyens de pronostic en Astrologie” by Max DUVAL [ed Traditionnelles, 1986, pp. 67-71] and a complete analysis in "A close look at tertiary progressions" by Elva Howson & Jack Nichols, [Considerations, vol XI-4, 1996; pp 3-12]- https://archive.org/details/considerations-21-1/considerations-11-4/page/n1/mode/2up. But here, I want to try to demonstrate the particular method advocated by Placidus. So:            
In the case of Wagner, Wieland, we observe:            
            
SU radix = 284° 27' 5" (284,45° CAP)            
            
MO radix = 71° 37' 30"° (71,63° GEM)            
            
∆ = |212° 49' 35"| (212,83° ) [ 17 tithi = ROUNDUP (∆/12)]            
            
Here is now the way in which Placidus would have proceeded: for 48 full years, 44 embolismic lunations are accomplished in 4 years after birth but with 33 days less, that is to say 11*4 since the moon covers 12 lunations in 11 days less than a whole year, as indicated in canon XL            
... if you wish to have a ready calculation of the progressions for several years, note that the moon does not complete twelve lunations in one whole year -i.e. a solar year - but in eleven days less. Having therefore the distance from the moon to the sun in the sky of birth, search for this eleventh day before the end of the first year of life and having found it, then know that the progression of twelve years of life is completed. Likewise 22 days before the end of the second year after birth gives the progressions accomplished for 24 years and so on' [De Progressionibus, op. cit., p. 54]            
Therefore on 5 Ja 1921, by removing 44 days, we arrive at 22 November 1921 [,,,] and then, the process is completed for 44 full years. Then, for the 1 other years elapsed during the twelve embolismic lunations, I arrive at 21 December 1921, for the remaining 0 months and 23,09 days (i,e, 23 days and 5,4 hours). I compute the tithi (exact distance between SU and MO radix) for the last time : the date of Embolismic Progression J0 is : 21 December 1921 at 13h 21min tu. Thereafter, i add to this date 23,09 d corresponding to 9,384M [see EVEN] :            
            
JD Pr Emb = 9,38 x 30 / (365.24 /29.53) = 23,09 D            
            
where 365.24 is the number of tropical days in a year and 29.53 is the average period for the synodic month of MO            
            
 trop days 365,242194775911 (1)            
            
syn month = 29,5305886734202 (2)            
            
where T = (JD-2451545)/36525            
            
In the present case JD = 2421233,5            
            
so, T = -0,829883641341547 (see formula 1 and 2)            
            
Finally, we find : date for J23,09D = 13 January 1922 at 16h 36min   local (15h 36min  TU).    

We now return to the problem we faced: should the graphical results be expressed in zodiacal or mundane terms? Let us examine this:

With the mundane system, we find :

LUNI-SOLAR PHASE            
---------------------------------------            
This is a method that we find outlined in Vettius Valens [book VI 9] as indicated by Anthony Louis in his blog :              
 'Vettius Valens had a different notion of annual returns. He felt that the return of the Sun each year was insufficient for forecasting for the year ahead because it omitted the influence of the the Sun’s partner, the Moon. As a result, Valens used a hybrid chart for the annual return which consisted of the positions of the planets when the Sun returned to its natal position each year but these positions were placed in a chart whose Ascendant and houses were determined by the moment the Moon returned to its natal degree during the zodiacal month when the Sun was in its birth sign.' [The Tithi Pravesh and its Monthly and Daily Iterations, November 5, 2022]              
Placidus uses it in his Primum mobile (Tabulae primi mobilis cum thesibus et canonibus 1657) and gives the procedure to follow in the XL canon (De Progressionibus, p. 53). A complete example appears in the analysis of the theme of Charles V (Exemplum Primum Caroli V. Austriaci Imperatoris, pp. 59-62).              
There is only one site on the internet that does this calculation:  https://horoscopes.astro-seek.com/calculate-planet-revolutions-returns/            
            
but it only gives the soli-lunar return at D0; Placidus continues the progression until end of process (i.e. even). For example in the case of François Ier, if we take the date of 31 Mar 1547, we must first translate this date into 'life-year equivalent': we find :            
---------------------------------------            
EVEN    48,3446340521707    48    Y
0    4,13560862604837    4    M
    4,06825878145099    4    D
    1,63821075482383    1    H
        38,29    M
---------------------------------------            
The method of “embolismic lunations” as a predictive technique :   See : Tabulae Primi Mobilis,,, Placido De Titis, Patavii, MDCLVII             
An embolismic lunation, correctly termed an embolismic month, is an intercalary month, inserted in some calendars, such as the Jewish, when the 11-days' annual excess over twelve lunar months adds up to 30. An arbitrary application of this was used by Placidus, who applied the term Embolismic Lunation, to a Figure cast for the moment of the Moon's return to the same relation to the Sun that it occupied at birth. It was made the basis for judgment concerning the affairs and conditions of the ensuing year of life.' [https://astrologysoftware.com/community/learn/dictionary/lunation.html]               
The solar year does not have a whole number of lunar months (it is about 365/29.5 = 12.37 lunations), so a lunisolar calendar must have a variable number of months in a year. Regular years have 12 months, but embolismic years insert a 13th "intercalary" or "leap" month or "embolismic" month every second or third year [...]. Whether to insert an intercalary month in a given year may be determined using regular cycles such as the 19-year Metonic cycle [...] or using calculations of lunar phases [...]. [wikipedia]               
The whole difficulty therefore comes from the fact that there is no overlap between the solar month (30 D) and the lunar month (synodic month 29.53), consequently between the solar year (365.242) and the lunar year (354.367).             
 'In Vedic timekeeping, a tithi is a "duration of two faces of moon that is observed from earth", known as milа̄lyа̄ [...] in Nepal Bhasa, or the time it takes for the longitudinal angle between the Moon and the Sun to increase by 12°. In other words, a tithi is a time duration between the consecutive epochs that correspond to when the longitudinal angle between the Sun and the Moon is an integer multiple of 12°. Tithis begin at varying times of day and vary in duration approximately from 19 to 26 hours. Every day of a lunar month is called tithi.' [wikipedia]              
We see that the interest of Placidus' method (outlined by Vettius Valens) comes from the fact that the individualisation structure of the progression system is no longer represented by a single point (solar return or lunar return) but by a distance ( in this case the distance between SU radix and MO radix).            
We find in the literature another method which is similar to that of the solilunar phase: it is the tertiary directions. We find a critique of it in “Les Moyens de pronostic en Astrologie” by Max DUVAL [ed Traditionnelles, 1986, pp. 67-71] and a complete analysis in "A close look at tertiary progressions" by Elva Howson & Jack Nichols, [Considerations, vol XI-4, 1996; pp 3-12]- https://archive.org/details/considerations-21-1/considerations-11-4/page/n1/mode/2up            
In the case of François Ier, we observe:            
            
SU radix = 253° 55' 39" (253,93° SAG)            
            
MO radix = 50° 58' 35"° (50,98° TAU)            
            
∆ = |202° 57' 4"| (202,95° ) [ 16 tithi = ROUNDUP (∆/12)]            
            
Here is now the way in which Placidus would have proceeded: for 36 full years, 33 embolismic lunations are accomplished in 12 years after birth but with 33 days less, that is to say 11*3 since the moon covers 12 lunations in 11 days less than a whole year, as indicated in canon XL            
... if you wish to have a ready calculation of the progressions for several years, note that the moon does not complete twelve lunations in one whole year -i.e. a solar year - but in eleven days less. Having therefore the distance from the moon to the sun in the sky of birth, search for this eleventh day before the end of the first year of life and having found it, then know that the progression of twelve years of life is completed. Likewise 22 days before the end of the second year after birth gives the progressions accomplished for 24 years and so on' [De Progressionibus, op. cit., p. 54]            
Therefore on 25 NOV 1501, by removing 33 days, we arrive at 24 October 1501 [,,,] and then, the process is completed for 33 full years. Then, for the 12 other years elapsed during the twelve embolismic lunations, I arrive at 9 October 1502, for the remaining 11 months and 19 days. I compute the tithi (exact distance between SU and MO radix) for the last time : the date of Embolismic Progression J0 is : 14 October 1527 at 8h 23min tu. Thereafter, i add to this date 10,18 d corresponding to 4,136M [see EVEN] :            
            
JD Pr Emb = 4,14 x 30 / (365.24 /29.53) = 10,18 D            
            
where 365.24 is the number of tropical days in a year and 29.53 is the average period for the synodic month of MO            
            
 trop days 365,242220451689 (1)            
            
syn month = 29,5305877606115 (2)            
            
where T = (JD-2451545)/36525            
            
In the present case JD = 2268531,5            
            
so, T = -5,01063655030801 (see formula 1 and 2)            
            
Finally, we find : date for J10,18D = 24 October 1527 at 12h 38min   local (12h 38min  TU).        
As I have already pointed out, it seems that the date J0 should be used for an event linked to a chronic illness and the terminal date (here 16.24 J) for a critical or acute event. In the case of François I, the illness (syphilis) had been present for many years.   


We find the aspect  ♄ ☍ {☉♂}.











URBANUS VII (2) - Soli Lunar phase (4)

 URBANUS VII (2) - Soli Lunar phase (4)


Pope Urban VII (4 August 1521 – 27 September 1590), born Giovanni Battista Castagna, was head of the Catholic Church, and ruler of the Papal States from 15 to 27 September 1590. His papacy was the shortest recognized in history. Giovanni Battista Castagna was born in Rome and died in Rome on 27 September 1590 of malaria. He had reigned for 13 days and died before he could be crowned. He was buried at St. Peter's Basilica. 
See also https://primarydirections.blogspot.com/2017/09/argoli-3.html


Argoli only explores directions touching the MC or the ASC; in the case of Urbaus, he shows that around the age of 69, we find ASC ◻ ♄ and MC ☌ ☉. If we compute the data, we find :


- OA ASC 163.53°
- OA ◻ ♄ (Z) 232.88°
-------------------------------
- diff 3.04 

Interested in Placidus's method (formerly known as the method of Al-Battani and Al-Biruni (see Schirmer, 1934, Encyclopedia of Islam) and fully theorized by Carlo Alfonso Nallino (Al-Battānī sive Albatenii Opus astronomicum, pp. 315-317; Nallino, Batt II, pp. 283-289 and I, pp. 131-134 III, 200-202), we studied the Primum mobile... published in 1657 and developed a process for writing a commentary on a direction under study "as if" Placidus was writing. A reference table is attached to it to track the parameters while reading.
If we now return to Argoli, we notice that while he focused on the study of axes, he completely neglected the interactions planetary. Let us therefore see in the case of Urbanus VII, what occurs in his birth chart on the date corresponding to September 27, 1590 (i.e. 150.74 or 69.15 in age).

The converse direction ◻ ☽ ☌ ♂ is found around 71.78 years (key EQU, 1.038).
 


 In our research, we hypothesised that the mundane chart alone should be considered; also we must base on the aspects taken in the semiarcs the research of the degrees likely to be considered in the duration of the life.
In the case of Urbanus VII we have the table above which allows us to estimate the breakdown of aspects between the different planets and the alchocoden.
When considering a theme, the first thing is to observe whether it is diurnal or nocturnal. In the case of Urbanus VII, it is DIURNAL.
In this case, the first point to check is SU. If  SU is well disposed, it can claim 1st stage to be HYLEG.

SU is Ru and therefore seems strong, with a dignity score of [13],
Moreover, when we look for the dignities that appear in the zodiacal inscription of SU, we find at least one
we find at least one aspect to match with the dignities
We'll see later what we get when we search for mundane dignities.
So : the hyleg is SU as dignity is Ru and aspect is conjunction

We note that SU is hyleg; it cannot be alchocoden because VE is in ☌ with it and moreover retrograde. VE does not exercise dignity over SU but the SU is itself in a condition of dignity (Ru). We are therefore in complete contradiction since there is inconsistency in the value of the link between SU ​​and VE. This inconsistency is reinforced by a mundane ∆ (radix) aspect between JU and VE.



Now we must look for the alchocoden: it is the planet which has the maximum dignity with regard to the hyleg and which exchanges a Ptolemaic aspect with the hyleg.
if we consider the MUNDANE system, we observe a conjunction aspect of SU.
At the same time, it appears that SU has  dignity of RUL over ASC.
So we have two possibilities with our hypothesis : first choose SU for hyleg ; second choose the MUNDANE system and try to find another couple of hyleg/alchocoden,
If we choose now SU we must know that no trad authority agree with this choice
In case of SU is the Hyleg, there is then one candidate to be the alchocoden: SU
First, we have to see which candidate has the most dignity: here, SU has candidate alcho dignities referring to SU : [RUL]
First, SU is linked with SU by a [conjunction] aspect and a [RUL] dignity,
However, SU is [Ru] and has a power of [13], and so SU has a good Kadkhudah score of [1]
SU is located at 140,62° at more than 5° from [Δ degrees cups sup [XI] : 28,03° (300)] and has a domitude Regio of : [328,03] for a latitude of [0°]
Now, we have to take account of the radix zodiacal aspects,
------------------------------------------------------
   VE 0 SU: -6     minus alcho dy (1,97)
------------------------------------------------------
Without any change, we find with SU as Kadhkhudah : Y = 38,7 as a result of SU SUCCEDENT years
But as SU is Ru, following William Lilly in Christian astrology, p, 115 (London, 1647) on his table of Fortitudes and debilities, we remove 1/5 of his value, as dignity for SU is   Ru     Or  (ie 0)
------------------------------------------------------
So, zodiacal Y =63,68
------------------------------------------------------
MUNDANE
Now we have to think about the hyleg to find: MO is not suitable; the rule is then in a nocturnal theme to reconsider first the case of SU,
In the mundane theme with  domification, we find a RUL :SU with a conjunction for SU
SU is in ruler
So the Y are in principle : 69
But, according to MONTULMO, the  alchocoden (SU) is in XI house and has two dignities in this house ; so  IX is cad and not cadBut, according to MONTULMO, if the  alchocoden (VE) is in IX house and has two dignities in this house ; so  IX is not is not considered as cadent but as succedent. It also appears more logical that house IX, adjoining the MC and hylegial, has a standard score at least equal to 2/3 of the succedent score.
So the actual Y is 69,
To do this, the procedure is not unequivocal but one of the most logical seems to me to be the one mentioned by Auger Ferrier in ‘Jugements astronomiques sur les nativités’, Rouen, 1583 (pp, 39-51 and notably pp, 43-48). Note that Auger Ferrier's comments appear directly related to those of Montulmo in his’ De Nativitatum liber praeclarisimus’ (Nuremberg, 1540), cap IV & VII. Book translated by Robert Hand (‘On the Judgment of Nativities’, part 1 & 2, Project Hindsight, vol X)
the years of life are identified for the [succ] and [cad] houses relative to the alchocoden

In September 1590, Giovanni Battista Castagna was elected pope under the name Urbanus VII. This moment is marked to within 3° by a conjunction between MC and {☉, ♀}. Besides this conjunction, there is a sextile between MC and ♃ (noted to by Argoli) and an ☍ between ♃ and {☉, ♀} (note that the opposition of ♃ is in principle beneficial, especially since a radix aspect in trine is there and ♃ is Ru).
 

15 days later, Urbanus VII died from possible malaria. 

I have already mentioned the squaring of AS and SA (noted by Argoli). Let us return to this converse direction ◻ ☽ ☌ ♂.

 Comment 'from Placidus' :

The direction of the MA in the locus of  □ MO by converse motion is calculated as follows:
the distance of □ MO counted from the IC (Immum Coeli) is 10,55° for its right ascension (RA) is 242,98° ; the pole's elevation of the III house and the IV is 17,03°, the semi-nocturnal arc (SA N) of □ MO is 109,38° of which ⅓ (double horary time) is 36,46°, that gives for □ MO a polar elevation of ≈ 5,04°
Note that the mundane position of the □ MO is PM = 8,68 (this is the ratio of 90° to the nocturnal semi-arc of 109,38° at the meridian distance of  10,55°). 
If we wanted to determine the Placidus domitude, it would be sufficient, depending on the altitude h of □ MO - the directing aspect - (actual h =-66,63), to compute : (h<0) 270-PM or (h>0) 90-PM, or in the present case dom = 81,32, or : 21,32 [ d, III ],
In any case, at this pole, the oblique ascension (OA) of the position □ MO is 189,22° (the ascensional difference DA of □ MO under the pole of MA is DA = -1,88°) and that of the MA at this same place is OD [MA] = 256,7 ° with its own declination ; by subtraction we obtain the arc of direction |67,48|°,
This table shows a Placidus direction programmed some 'old-fashioned' with the distance of □ MO from the cusp of 3 (7,66), the width of 3 (36,46) established by double HT. We then find the DEC (-20,3), the DA of □ MO under the pole of cusp 3 3, RA and OA of □ MO. We then calculate the PM of □ MO (8,68)

Regio comment

The direction of □MO in the place of MA by converse motion is calculated as follows :
First of all, it must be considered that the so-called immobile positions of the theme are the significators: these positions (and their aspects on the ecliptic) are driven by the movement of the primum mobile and are called promissors. There is an ambiguity here that we have repeatedly raised: if we draw up a horoscope within 2 hours (let's say) following birth and according to what we have just stated, we observe that it is the significator that "seems" to have moved while the promissor "seems" to have remained immobile. We must never forget this ambivalent feeling when practicing the art of direction.
It should now be noted that the circle of position of a star is strictly the same in the Campanus and Regiomontanus houses (as Max Duval pointed out (in ‘la domification et les transits’, p, 33, Ed Traditionnelles, 1984)) and that only the "registration numbers" of the domitudes change (they are not expressed in degrees: Christophe Vitu has noted (http://mapage.noos.fr/astrolabe/latitude.htm#Domitude): 

"It is by abuse of language that we note the domicile in degrees, because this only really represents a measurable angle for a star located on the equator, in this case the diurnal arc is worth 180° (12 hours), and the domitude then corresponds to a sort of hourly angle which would be measured in the direct direction from the East point. In all other cases the domicile cannot be assimilated to an angle, its values ​​go from 0 to 180 for nocturnal houses and from 180 to 360 for diurnal houses, the culmination being identified by the value 270, each house worth 30."

The domitudes are linked by the relationship: 

tan d Regio = tan d Campa/cos ⅄, 

Henri Selva (‘La domification ou construction du thème céleste en astrologie’, Vigot ed., 1917, réed Lacour/Rediviva, 1992, p, 15) noted that Campanus' method is quite similar... to the 'rational method' (Regiomontanus)

Luni-Solar Phase

This is a method that we find outlined in Vettius Valens [book VI 9] as indicated by Anthony Louis in his blog :              
 'Vettius Valens had a different notion of annual returns. He felt that the return of the Sun each year was insufficient for forecasting for the year ahead because it omitted the influence of the the Sun’s partner, the Moon. As a result, Valens used a hybrid chart for the annual return which consisted of the positions of the planets when the Sun returned to its natal position each year but these positions were placed in a chart whose Ascendant and houses were determined by the moment the Moon returned to its natal degree during the zodiacal month when the Sun was in its birth sign.' [The Tithi Pravesh and its Monthly and Daily Iterations, November 5, 2022]              
Placidus uses it in his Primum mobile (Tabulae primi mobilis cum thesibus et canonibus 1657) and gives the procedure to follow in the XL canon (De Progressionibus, p. 53). A complete example appears in the analysis of the theme of Charles V (Exemplum Primum Caroli V. Austriaci Imperatoris, pp. 59-62).              
There is only one site on the internet that does this calculation:  https://horoscopes.astro-seek.com/calculate-planet-revolutions-returns/            
            
but it only gives the soli-lunar return at D0; Placidus continues the progression until end of process (i.e. even). For example in the case of Urbanus VII, if we take the date of 27 Sep 1590, we must first translate this date into 'life-year equivalent': we find :

The method of “embolismic lunations” as a predictive technique :   See : Tabulae Primi Mobilis,,, Placido De Titis, Patavii, MDCLVII             
An embolismic lunation, correctly termed an embolismic month, is an intercalary month, inserted in some calendars, such as the Jewish, when the 11-days' annual excess over twelve lunar months adds up to 30. An arbitrary application of this was used by Placidus, who applied the term Embolismic Lunation, to a Figure cast for the moment of the Moon's return to the same relation to the Sun that it occupied at birth. It was made the basis for judgment concerning the affairs and conditions of the ensuing year of life.' [https://astrologysoftware.com/community/learn/dictionary/lunation.html]               
The solar year does not have a whole number of lunar months (it is about 365/29.5 = 12.37 lunations), so a lunisolar calendar must have a variable number of months in a year. Regular years have 12 months, but embolismic years insert a 13th "intercalary" or "leap" month or "embolismic" month every second or third year [...]. Whether to insert an intercalary month in a given year may be determined using regular cycles such as the 19-year Metonic cycle [...] or using calculations of lunar phases [...]. [wikipedia]               
The whole difficulty therefore comes from the fact that there is no overlap between the solar month (30 D) and the lunar month (synodic month 29.53), consequently between the solar year (365.242) and the lunar year (354.367).             
 'In Vedic timekeeping, a tithi is a "duration of two faces of moon that is observed from earth", known as milа̄lyа̄ [...] in Nepal Bhasa, or the time it takes for the longitudinal angle between the Moon and the Sun to increase by 12°. In other words, a tithi is a time duration between the consecutive epochs that correspond to when the longitudinal angle between the Sun and the Moon is an integer multiple of 12°. Tithis begin at varying times of day and vary in duration approximately from 19 to 26 hours. Every day of a lunar month is called tithi.' [wikipedia]              
We see that the interest of Placidus' method (outlined by Vettius Valens) comes from the fact that the individualisation structure of the progression system is no longer represented by a single point (solar return or lunar return) but by a distance ( in this case the distance between SU radix and MO radix).            
We find in the literature another method which is similar to that of the solilunar phase: it is the tertiary directions. We find a critique of it in “Les Moyens de pronostic en Astrologie” by Max DUVAL [ed Traditionnelles, 1986, pp. 67-71] and a complete analysis in "A close look at tertiary progressions" by Elva Howson & Jack Nichols, [Considerations, vol XI-4, 1996; pp 3-12]- https://archive.org/details/considerations-21-1/considerations-11-4/page/n1/mode/2up            
In the case of Urbanus VII, we observe:            
            
SU radix = 327° 25' 18" (327,42° AQU)            
            
MO radix = 43° 28' 57"° (43,48° TAU)            
            
∆ = |283° 56' 20"| (283,94° ) [ 23 tithi = ROUNDUP (∆/12)]            
            
Here is now the way in which Placidus would have proceeded: for 60 full years, 55 embolismic lunations are accomplished in 9 years after birth but with 33 days less, that is to say 11*5 since the moon covers 12 lunations in 11 days less than a whole year, as indicated in canon XL            
... if you wish to have a ready calculation of the progressions for several years, note that the moon does not complete twelve lunations in one whole year -i.e. a solar year - but in eleven days less. Having therefore the distance from the moon to the sun in the sky of birth, search for this eleventh day before the end of the first year of life and having found it, then know that the progression of twelve years of life is completed. Likewise 22 days before the end of the second year after birth gives the progressions accomplished for 24 years and so on' [De Progressionibus, op. cit., p. 54]            
Therefore on 3 AUG 1526, by removing 55 days, we arrive at 10 June 1526 [,,,] and then, the process is completed for 55 full years. Then, for the 9 other years elapsed during the twelve embolismic lunations, I arrive at 26 February 1527, for the remaining 8 months and 21 days. I compute the tithi (exact distance between SU and MO radix) for the last time : the date of Embolismic Progression J0 is : 2 February 1527 at 15h 11min tu. Thereafter, i add to this date 4,43 d corresponding to 1,8M [see EVEN] :            
            
JD Pr Emb = 1,8 x 30 / (365.24 /29.53) = 4,43 D            
            
where 365.24 is the number of tropical days in a year and 29.53 is the average period for the synodic month of MO            
            
 trop days 365,242219061458 (1)            
            
syn month = 29,5305878104754 (2)            
            
where T = (JD-2451545)/36525            
            
In the present case JD = 2278831,5            
            
so, T = -4,78375085557837 (see formula 1 and 2)            
            
Finally, we find : date for J4,43D = 7 February 1527 at 1h 29min   local (1h 30min  TU).    

At this stage, we find the aspect :  ♂ ◻ {☉, ♀} which is perfectly in agreement with what we wrote above. It is likely that Giovanni Battista Castagna was ill before his election, in which case the soli-lunar phase would have to be postponed to D0 of the current cycle:

 


 Using the same process, we find the date of 2/2 1527 at 16:0 p.m. UT for J0. The aspects are more important: we find the 
♂ ◻ {☉, ♀}, we add to it ♀ ☌ ♄ and an echo direction ☽ ◻ ♃ et  ◻ ☽.
