Basil Valentine contemplates a chemical jar containing homunculi of a man and woman holding hands, and a child emanating from them (alchemical symbol of conception); he is suddenly visited by Sabine Stuart de Chevalier, who reveals that she has the key to his works and crowns him as the king of alchemists. Etching by J. Le Roy, ca. 1781, after Hostoul after Sabine Stuart de Chevalier.
