Pelias was the aged king of Iolcus who sent Jason, his brother's son, on the quest for the Golden Fleece. When Jason returned, Pelias refused to acknowledge him as heir to the throne. Medea brought about Pelias' doom. She told Pelias' daughters that she could restore their father's youth. To demonstrate her power, she cut up an old ram and threw it into a pot and boiled it, whereupon a young ram then jumped from the pot. This inspired Pelias' daughters to cut their father into pieces and throw him into a pot; he did not come out of the pot.
