An astrological chart applied to the reading of Tarot, derived from the book of Etteilla, Manière
De se récréer avec le jeu de cartes nommées tarots (1785).


https://books.google.com.tr/books?id=7Y ... &q&f=false

In terms of translation, looks pretty straight forward (I am pretty au fait with astrology, so perhaps that is why it seems easier to follow than some of his other works), at least in comparison with the first cahier (in which I find the numerical references very confusing and hard to follow!)

My feeling about Numbers and pythagorism in Tarot

Etteilla and disciple's pythagorism is indeed of interest.
Yet I am quite sure that they did rely on what I would call an elementary pythagorism at best reduced to the Decade and to triangular figurated numbers such as 78 = 1+2+3+5 +6 +7+8+9+10+11+12
They had no intuition of pentagonal numbers and their figurate expression.

The Arithmological Tarot - though it still remains alike an "invisible" matrix, only because there is, yet, no evidence discovered of it in the times of the standardisation of the deck and related to it, remains as a clear reference to Triangular, Square and Pentagonal figurate numbers in a "whole".

On one part , a Tetractys game with 4 Tetractys of Numerals and 4 Tetrads of Honours (counted possibly as 1 2 3 4) in 4 Emblems.
On the other part, 22 allegorical figures expanded as :
1+4+7+10 = 22

The modern attempts are in the spirit of Etteilla's pythagorism.
They finally reduce the Pentagonal 22 to 2 Decades +2,
This is an elementary Pythagorism,
It is orthodox because it views the expansion of numbers as an arithmetical succession of Decades. This is in conformity with Nicolas de Cuse.
But is does not take in account the figurate pentagonal expansion of Number 22 and simplifies this Pentagonal figurate geometrical expansion of Number 22 to an elementary Pythagorism of a Decimal Numeroly(10+10+2)

We know from the philosophers game that Pythagorean proportions were in use as a strategy to win a game.
These notions of Harmonia were far more complex than the very simple arithmology of the Pentagonal 22;
1 Unity
4 Tetrad
7 Septenaire
10 Decade

So if I understand that Occultists or Moderns do not understand or find too complex pentagonals figurate numbers, I m not sure at all, that in the time and space of the birth of Tarot, close to learned people aware of Pythagorism or close to the Platonician Medicean Academy, these notions would have been unknowned or seemed far fetched ...

In French sorry.

"Dès le IXème siècle nombreuses étaient les copies de son « De institutione arithmetica » dont les spécialistes, même s’ils s’accordent à la trouver inspirée de Nicomaque (mathématicien du Ier siècle, originaire de Palestine),
reconnaissent que Boèce a su y pousser à l’extrême sa science des nombres.

I'll be away a little time...

Meanwhile, i ll share my actual intuition .

I am looking for a Christian learned Pythagorean aware of figurate numbers and interested in games in the last quarter of the XVth centuy or the very beginning of the XVIth in Italy - circa the period of Cardinat of Cardinalat of Giuliano della Rovere Pope 1503 as Jules II (correction added 14/02)- and from there exploring his relations.

For the moment, I have found Fra Luca di Paccioli related to Leon_Battista_Alberti in 1471 (1496 he meets Leonardo da Vinci)

Nota
A "Golden" curiosity ?
BtW the 78 cards can also be divided in two series :
56 the Tetractys Game with 2 series of 2 "suits" (?) that is 56 = 2x (14x2=28)
22 the Pentagonal pogression of the iconographical figures.
56 and 22 are not in a Golden Ratio.
But are these numbers really random?
No. These Numbers (22) and (56 as 28x2) are nevertheless related to the square root of PHI .

56/2 ) = 28 divided by 22 = Square Root of PHI

PS : Square root of PHI (also called Golden Number) = 1,272 with PHI as 1.16179 circa real value as 1.618
Reminder : PHi also called Golden number : (1 + square root of 5) divided by 2 = circa 1.618

Corrections 14/02 underlined

For the moment , appearently nothing about Pentagonal numbers as 22 in Tarot. But, we have a high learned Pythagorician (maybe the best), Paccioli, interested in games such as chess in a Pythagorean approach, fan of card magic tricks, with Isabelle 'Este in Mantoua linked to cards and trionfi, in 1500 under Cardinalat of Giuliano della Rovere ., five years before the apparition of the word "tarocchi" (D'Este) or "taraux" in Avignon ....
[BtW why do I speak about the Cardinalat of Giuliano della Rovere : because this englobes his first cardinat in Avignon also...another thread of interest still at work - may well become of interest to understand the simultaneity of the appearance of tarrochi (Este) and taraux (Avignon) two years after his nomination to Pontificat in 1 Novembre 1503 as Jules II)
https://fr.wikipedia.org/wiki/Jules_II
viewtopic.php?f=11&t=691&hilit=bougearel

Hmmmm!
Right time, right place, right persons ...of interest for sure! No?
At least, it legitimates a deeper inquiry, i believe.
Paccioli did not write a manuscript a about Tarot like he did about Chess.
But he knew about cards.
Did he or close relatives influence for a Pythagorean standardisation to 22 for the Iconografical figures?

Connection Boiardo / Viti as well as the Urban court via Emilia PIA.
(Young Pietro Bembo is already there debating with Emila PIA. He'll have as teacher in 1492 the long living Byzantin Constantin Lascaris (1434-1501), the preceptor of Francisco Sforza in Milan and close to Bessarion )

Rappel : Constantin Lascaris

The "overlooked" figure of Emilia PIA - she first appears in an still obscur for me connection with Boiardo and VIti : Huck had found the information but I ve lost the link and she appears after close to Isabelle d'Este and becomes the confident of the Lady of Urbino.

Where is this from?

The question is, were Pentagonal Numbers part of the standard quadrivium of the time or not? If so, anybody could have applied the numbers connected with them to the cards.

What is then important is the number 5, for pentagonal. It is for the fifth suit, the one that shows the way to God, an especially sacred number, of the Pope card and of the various sacred associations to the number that made it particularly holy. For example Augustine: the five wise virgins, who have abstained from unlawful use of the five senses (http://www.newadvent.org/fathers/160343.htm); the "five books of Moses", the "five porches containing the sick folk", the "five loaves feeding the five thousand" (https://books.google.com/books?id=wIp0A ... ve&f=false), and the five stigmata of Christ, the same repeated for Francis of Asissi (https://en.wikipedia.org/wiki/Stigmata).

But perhaps some author emphasized pentagonal numbers for some reason. If so, the relevant passage needs to be found.

One thing: Julius was not a Medici; he was a della Rovere (https://en.wikipedia.org/wiki/Pope_Julius_II). The Medici popes were after him.
