Funny, none of the options apply to my view, so I could not answer the poll question; but I will comment anyway.
It is quite clear to me that the source of tarot trumps is a tradition surrounding letters, but not Hebrew letters directly, as they are demonstrably based on the tree-letters of Brito-Irish bardic tradition, to which they are correlated by their numbering there, not by their Hebrew or Greek numbers, bardic tradition having come to the Continent riding on the back of the 'matter of Britain'—although after reading Filipas I would not rule out another layer of symbolism related to Hebrew numbering as well (probably as a blind).
The bardic letters themselves do have a one-to-one correspondence with Hebrew letters, a fact that becomes particularly apparent upon application of Graves's hypothesis of two letters not included in the 20-letter ogham sequence (in other words, that were kept secret), one of which is Ii (double I), standing for mistletoe (ixias in Greek) or loranthus: these hover above ground (rooted in trees), just as square-Hebrew yod hovers above the line on which one writes. The correlations are often quite striking, as with Q, quert the apple, which still has the form of fruit-with-stem.
Certain facts arising directly from Hebrew letters do inform the trumps, though. For the bards knew both alphabets (and Greek, of course). One rather vivid example is trump II LaPapesse (in the original deck, that is, meaning the Marseilles). The hangings above her on this trump combine with the oblong shape clasping together her cloak to produce the shape of lovers (their loins, anyway) about to engage in the carnal act (to which seated Papess is, of course, oblivious), with the oblong shape being the erect phallus of the male, specifically a circumcised phallus: this is because by bardic numeration 2 is E, eadhe, quivering aspen, which corresponds to the letter heh in Hebrew, which was the letter added to Abram to make Abraham to mark the covenant of circumcision. Moreover, its place among the twelve 'simple letters' is scorpio, the privates (as hinted in its being 'quivering' aspen, symbol of extreme sensitivity), though in the reordering of letters represented by the alef-bet, it has moved to aries.
The above statements can all be backed up by exhaustive argument, of course (or I wouldn't say them). I’ll shut up now, but I thought my perspective might be of interest to someone out there.
