Notes: A resetting of the 1st French ed. of 1624. Basil Valentine's Douze clefs apparently first appeared as Practica cum XII clavibus in Michael Maier's Tripus aureus (Frankfurt, 1618). His Azoth first appeared as Aureliae occultae philosophorum partes duae in Caillet's Theatrum chemicum, 1613. Cf. Yale, Alchemy.

T.p. date of l'Azoth is 1659.

Les douze clefs has symbolic engraved frontispiece. In addition, each of the 12 "clefs" is accompanied by a symbolic engraved plate signed: I. Gobille fecit. L'Azoth has separate t.p.'s for the work as a whole and for the Seconde partie, both with woodcut vignettes. Its ill. are in-text symbolic woodcuts. L'Azoth has separate pagination and signing.
