From the Greek name
Ιασων (Iason), which was derived from Greek
ιασθαι (iasthai) "to heal". In Greek mythology Jason was the leader of the Argonauts. After his uncle Pelias overthrew his father
Aeson as king of Iolcos, Jason went in search of the Golden Fleece in order to win back the throne. During his journeys he married the sorceress
Medea, who helped him gain the fleece and kill his uncle, but who later turned against him when he fell in love with another woman.
