Nicholas Flamel belongs to alchemy exclusively, and he enters only into our consideration because of the hieroglyphical book of Abraham the Jew, in which the scrivener of the rue Saint-Jacques-la-Boucherie found the absolute keys of the Great Work. This book was founded on the Keys of the Tarot and was simply a hieroglyphical and Hermetic commentary on the _Sepher Yetzirah_. We find as a fact, by the description of Flamel himself, that the leaves were 21 in number, making 22 with the title,[246] and that they were divided into three septenaries, having a blank leaf at every seventh page. Let us here bear in mind that the Apocalypse, that sublime Kabalistic and prophetic summary of all occult types, also divided its symbols into three septenaries, between each of which there is silence in heaven, thus instituting a striking analogy with the uninscribed leaf in the mystic book of Flamel.[247] The septenaries of the Apocalypse are (_a_) seven seals to open, meaning seven mysteries to be learned and seven difficulties to be overcome; (_b_) seven trumpets to sound, being seven utterances to understand; (_c_) seven vials to empty, which signify seven substances which must be volatilised and fixed. In the work of Flamel the first seventh leaf has as its hieroglyphical character the wand of Moses overcoming the serpents brought forth by the magicians of Pharaoh. They are seen devouring one another, and the figure as a whole is analogous to the Victor of the Tarot, yoking to his cubic chariot the white and black sphinxes of Egyptian Magic. The symbol in question corresponds to the seventh dogma in the creed of Maimonides: we acknowledge but one prophet, who is Moses. It represents the unity of science and the work; it represents further the Mercury of the Wise, which is formed by the dissolution of composites and by the reciprocal action of the Sulphur and Salt of metals. The emblem on the fourteenth page was the Brazen Serpent set upon a cross. The cross represents the marriage of the purified Sulphur and Salt, as also the condensation of the Astral Light. The fourteenth Trump card in the Tarot depicts an angel, who is the spirit of the earth, mingling the liquids in two ewers, one of gold and one of silver. It is the same symbol formulated after another manner. On the 21st leaf of Flamel’s book there was the type of space and universal life, represented by a desert with springs of water and serpents gliding hither and thither.[248] In the Tarot, space is typified by the four signs allocated to the cardinal points of heaven, and life is represented by a naked girl dancing in a circle. Flamel does not specify the number of springs and serpents, but the former would probably be four, springing from one source, as in the Pantacle of Eden; the serpents would be four, seven, nine or ten.
