"As it is said in Genesis, the Spirit of Elohim thus hovers above the dark waters, as the impenetrable master of the swirling of the cosmogonic Wheel. Severe, placid, forever enigmatic, the eternal Sphinx remains master of its secret, which is the Great Arcanum, the creative Word hidden from creatures, the initial Yod of the divine Tetragrammaton."
Le tarot des imagiers du Moyen-âge by Oswald Wirth, c. 1926-1927
