Discours philosophique sur les trois principes animal, végétal et minéral, ou, La clef du sanctuaire philosophique
This is an 1781 alchemy treatise published in Paris by François-Augustin Quillau, with its plates engraved by Jacques Le Roy and written by the Chevalier Sabine Stuart de Chevalier for readers of philosophical and occult texts. The first picture is a copperplate of a winged figure above a helmeted warrior with a serpent and a lion-like beast at his feet, engraved in fine line with an allegorical mood; the second is a small vignette of the Capitoline she-wolf on a carved pedestal above a banner, which a designer could use for classical emblem borders and pedestal layouts.
