435 Sabine Stuart de CHEVALIER. Discours philosophique sur les trois principes, Animal, Végétal et Minéral. Ou la clef du sanctuaire philosophique. Par Sabine Stuart de Chevalier. Cette Clef introduit celui qui la possede dans le sanctuaire de la Nature; elle en découvre les mystères; elle sert en même temps à dévoiler les Ecrits du célèbre Basile Valentin, & à le défroquer de l'Ordre respectable des Bénédictins, en donnant la véritable explication des douze Clefs de ce Philosophe ingénieux. 12° Paris: chez Quillau 1781 Ferguson Young [Illustrations:- 1. Inserted before page i following the preface. Engraving. 131x73mm. A laboratory furnished with books, and an organ with seven planetary pipes, looks out upon a garden with a maze and a tree bearing apples. A monk sits at a chimney bearing the symbols of the four elements, holding a cloth to his face. A woman or goddess appears placing a crown over the head of the monk. He seems to be pushing her away. In her left hand she holds another crown, a sceptre, and a key. Beside the chimney is a small furnace upon which a flask is set. Within this flask are a king a queen, reminiscent of the 'Donum Dei' series, and three stems of a plant with rounded fruits protrude from the neck of the flask. This illustration has an explication on pages i-iv. "Sabine Stuart de Chevalier im. Hostoul del. Ja le Roy sculp." 2. p203. Engraving. 131x72mm. A young prince with crown stands upon the back of a three headed dragon which he has pierced with his sword. From this wound various snakes crawl away. A winged angel appears from out of a cloud and places a laurel wreath on the head of the prince. An explication follows on pages i-iv. "Sabine Stuart de Chevalier im. Hostoul del. Ja le Roy sculp."]
