Cleopatra the Alchemist

Cleopatra the Alchemist (Greek: Κλεοπάτρα; fl. c. 3rd century AD) was a Greek alchemist, writer, and philosopher. She experimented with practical alchemy but is also credited as one of the four female alchemists who could produce the philosopher's stone. Some writers consider her to be the inventor of the alembic, a distillation apparatus.

Cleopatra the Alchemist appears to have been active in Alexandria in the 3rd century or 4th century A.D. She is associated with the school of alchemy typified by Mary the Jewess and Comarius. These alchemists used complex apparatus for distillation and sublimation.
