Coming back to a post of 2011 of Huck about maybe the oldest evidence of a 22 structure dated 1450 ?

viewtopic.php?f=11&t=663#p9888

### Re: Le Tarot arithmologique - la séquence 1+4+7+10 = 22

#472There is more than one source for the relevant lot-book type ...

Conradus Bollstatter version ... c. 1450, 22 animals, with astrological context

Fränkisches Losbuch c. 1425-1450, 22 identical animals, with astrological context

Printed version of 1520, 22 animals, with astrological context

------------------

Each of these has minor variants in the row of the animals against the 2 others.

Each uses 22 questions, 22 Kings, 22 Prophets and 22 animals.

Then there is a Trier-version with differences in the figures, c. 1515

And a version with 32 animals, which includes all 22 animals of the upper three versions. It's suggested, that it was made in the time of Ludwig III von der Pfalz, who died 1437 and reigned since 1410.

The Splendor Solis (c. 1530, 22 pictures) has distant similarities in its astrology.

All these works appeared in Southern parts of Germany.

Parts of the astrological system look, as if they are very old, reaching back to astronomical ideas between 500 BC- 70 AD (a 13th zodiac sign looks, as if it has developed from a 13-months-calendar; two months in 59 days)

Or it might be just relatable to a religious Jewish calendar, which was very old and still was used. Lot book systems were often imported from Eastern versions.

Italy likely hadn't much lot books. When Lorenzo Spirito made one (maybe 1473, probably 1482), it didn't get a 22x22x22x22-scheme, but a 20x20x20x20-scheme. It became a big success .. many reprints.

I would not argue for any influence upon the tarot of Kabbalah, with its evident affinities to Pythagoreanism before Pico. He was its great popularizer. However it is not true that Pico was the first Christian humanist to learn about Kabbalah.

Alain : Well, I failed to explain myself.

Let's go back to the beginning on this issue.

Decker's take about the succession of decades ad infinitum

I wrote it was orthodox to present the series of numbers this way.

But that this manner did not (enough?) take in account the pythagorean figurative geometry of Number 22 as an expansion 1+4+7+10.

Could there be a way of conciliating the two lectures?

Nicolas de Cuse shows very well the succession of the Decades ad infinitum (though he stops his example at one thousand)

"

...

In Tarot the Numericals are 4 Decades :

40 =10 +10+10+10

Counting the numbers of the Emblems on each card of each Decade :

220 = 55+55+55+55

(In modern Maths, we'd say that 10 is the 'Triangular Root' (?) =

Nombres 1 2 3 4 5 6 7 8 9 10

Racine triangulaire 1 3 6 10 15 21 28 36 45 55)

The Decade is repeated 4 times.

So this is the relation :

- between the Number 40 and 220

- between the Number 10 and 55

Though the Number 220 is not cited in the

1+2+3+4+5+6+7+8+9+10 = 55

This specific pythagorean summation of the ten first numbers of the Decade as 55 is repeated 4 times in the Four Decades of the Tarot's numericals.

55x4

From my point of view, it is not random that the result of the summation is 220 = 55x4

This is , in my mind, an indication of a relation of the Decade (Suits Numericals) to the 22 Trumps and vice-versa.

22x10 or 10x22

Nota : there is also the Tetrade of the 4 Honours repeated 4 times in the 4 Emblems

Giving value 1+2+3+4 to them, we'd have the 4 Tetractys specific of the 4 Emblems.

Post scriptum

Though in a different take, it is also of interest that the structure of 22 repeated 4 times was also present in these times

En effet, à partir du nombre dix, qui est une unité de second ordre, le déploiement au carré de la racine dix est atteint par une progression similaire en quatre étapes : 10, 20, 30, et 40, qui additionnés font 100, carré de la racine 10.

Serie of Numbers : 22 = 1,5,12,22

I was only able t access to section 13.

Sections 14 is blank!

InsT. Arith. II, 13

p.97 paragraphe XIII

Also on :

II, 17 p.101 paragraphe XVII

PS Maybe something of interest looking through these references in English..

### Re: Le Tarot arithmologique - la séquence 1+4+7+10 = 22

#480Math has always something to do with games .. that's normal.

However, it's a rather stupid phantasy, to call anything what has to do with math "Pythagoreanism". That's simply incorrect history. The use of math existed before Pythagoras. And the "Pythagorean Theorem" wasn't invented by Pythagoras.
