Adamantius

, a Greek physician and sophist of the fifth century, was originally a Jew, and lived at Alexandria. He then went to Constantinople, and became a Christian. He dedicated to the emperor Constantine a work in two books on Physiognomy, which has descended to our days, and has often been reprinted, particularly in Sylburgius’s edition of Aristotle, and among the “Physiognomonire veteres, Gr. Lat. cura J. G. Franzii,” Altenburgh, 1780, 8vo, a work of great accuracy. ³
