His father committed suicide by drinking bull's blood, an act which prompted the murder of this man's brother Promachus. This man ordered the construction of a pentekontoros built partly using wood from the oak grove at Dodona and employed the advice of Phineas in order to pass through the (*) Symplegades. While helping a disguised Hera cross the Anauros river, he lost a sandal, thus fulfilling a prophecy involving his usurping uncle Pelias. During a trip to Colchis, this man plowed a field using fire-breathing oxen and, like Cadmus, defeated warriors grown from dragon's teeth. His second wife Glauce was jealously killed by his first wife, the sorceress Medea. For 10 points, name this hero who led the Argonauts in search of the Golden Fleece.
