who fulfilled the warning beware of the man with one sandal
Pelias Many years later, Pelias offered a sacrifice by the sea in honor of Poseidon. Jason, who was summoned with many others to take part in the sacrifice, lost one of his sandals in the flooded river Anaurus while rushing to Iolcus. In Virgil's Aeneid, Hera had disguised herself as an old woman, whom Jason was helping across the river when he lost his sandal. When Jason entered Iolcus, he was announced as a man wearing one sandal. Fearful, Pelias asked Jason what he would do if confronted with the man who would be his downfall. Jason responded that he would send that man after the Golden Fleece. Pelias took Jason's advice and sent him to retrieve the Golden Fleece. It would be found at Colchis, in a grove sacred to Ares, the god of war. Though the Golden Fleece simply hung on an oak tree, this was a seemingly impossible task, as an ever-watchful dragon guarded it.[3]
