The tarot's correspondence with the Tree is documented; this ten-card layout over it is modern practice with no first publication yet located.
Marked unsourced deliberately. The correspondence is well attested and the SPREAD is not, and collapsing the two would borrow the authority of the first for the second. SEARCHED AGAIN IN OCTOBER 2026, AND IT STAYS UNSOURCED, but it is no longer uncited. Quareia teaches exactly this layout — one card to each of the ten spheres, the two outer pillars read as what is flowing in and what is flowing away, the middle pillar as the course of the matter — and it is cited below. A 2014 course cannot be a first publication, so it is evidence of WHAT THE LAYOUT IS and not of where it came from; the distinction is the whole reason this claim exists. The nearest earlier thing found is Rachel Pollack, who says on her own weblog that she first described using the Tree as a tarot spread in 78 Degrees of Wisdom (1980), and who credits Gail Fairfield for it. That is NOT this layout: hers is a full-deck reading dealing all 78 cards into eleven positions, the ten spheres plus Da'ath, about seven cards to a position. It is recorded here because it is the closest near-miss and because a later reader will otherwise find it and assume it settles the question.
