About Demetrios Chloros

Demetrios Chloros was a Byzantine physician and astrologer.

Demetrios Chloros was a 14th-century Byzantine physician, astrologer, priest and sorcerer who was tried for possessing magic books.

Chloros was a protonotarios, or secretary of the patriarch, and former kanstresios, supervisor of offerings. He was put on trial by the patriarchate of Constantinople because he had transcribed texts with content pertaining to magical practices, including the Coeranis, a portion or all of the Cyranides, and a notebook of invocations and spells he had compiled himself, Chloros defended the texts on the basis of their medical value. Other physicians who were witnesses against him called Chloros a disgrace to the art of medicine and said he insulted Hippocrates and Galen by regarding them as magicians. Chloros was subsequently sentenced to live as a monk under surveillance in the monastery of the Peribleptos.

Chloros is known to have vacillated between Orthodoxy and Catholicism. The synodal decree that condemned him gives equal weight to recounting his ecclesiastic career and his movements between Constantinople and the papal court. Since other churchmen advertised themselves as knowledgeable occult practitioners, the mere possession of magic texts is not likely to have been the true or primary cause of action against him.

Evidence in a later case against a physician named Gabrielopoulos included the discovery at his home of a book of spells by Chloros and the Cyranides.
