Court Card Decanates

[Vod-Vil]

I have a question about this statement from Liber Theta.

"Simultaneously, 12 of these 16 cards correspond to a particular 30° segment of the zodiac:
the first two decanates (i.e., the first 20°) of one sign, of the element to which the card’s suit corresponds,
and the last decanate (or 10°) of the preceding sign, which is of a contrary element."

**Who figured this out? **

Was the 20 degree/10 degree theory worked out before Court de Gebelin started pairing the Hebrew alphabet with the Trumps?

I can’t answer your question of origins, bit I can tell you that the difference between the two reoresents two distinct meditations, and there is no competition between the two for correctness.

I came to the forum after long-time-no-see with a question in mind to post and randomly checked here in Qabalah section to see what's new - to find this old thread that addresses, however in its own different way, exactly the subject of my question !

Does anyone know (ideally, historical info, with year/century and everything pertinent) when the Shemhamphorash started being attributed to the Zodiac, in sequence as we now have it?
