A human body is consumed by a furnace; a woman holds a small red limbless effigy bearing a crown; a man holds a sheaf, and another a stick; below, by another furnace, a green and red dragon face each other, poised for combat; representing a stage in the process of alchemy. Coloured etching, ca. 18th century.
