ユスティノス
Simon Magus, also known as Simon the Sorcerer and Simon the Magician, came from the village of Gitta (also spelled Getta) in Samaria, according to Justin Martyr; a site settled by the tribe of Dan according to Josephus. Justin, who was himself a 2nd-century native of Samaria, wrote that nearly all the Samaritans in his time were adherents of Simon. Surviving orthodox texts, such as those of Irenaeus, Justin Martyr, Hippolytus, and Epiphanius, regarded Simon as the source of all heresies, including Gnosticism.
