“There will soon be a time when the tragic actors will believe that their masks and costumes are their real selves. You have these things as material and a plot. Say something so we may know whether you are a tragic actor or a comedian. For they have the rest of their material in common [apart from the words]. If one, then, should deprive the actor of his buskins and his masks and introduce him to the stage as only a ghost, has the actor been lost or does he remain? If he has a voice, he remains.”
The typical tale of Medea has her trick the daughter’s of Pelias–the man who deprived Jason of a kingdom–into killing their father. She cuts and boils an old goat, mixes in some drugs, and a young goat emerges. The daughters of wicked Pelias try to do the same as a surprise for their father. And, surprise, they get daddy stew.
The scholia to Euripides’ Medea record other traditions where Medea uses her magic.
Schol ad Eur. Med. Arg. 10-22
“Pherekudês reports that Mêdeia made Jason young again by boiling him. The poet of the Nostoi says about his father Aisôn:
[She] quickly made Aison a dear young man
After wiping away old age with her clever plans
By boiling him with many drugs in a golden container.
Aiskyulos in his Nurses of Dionysos recounts that she also remade Dionysos’ nurses along with their husbands by boiling them. Staphulos says that Jason was killed in a certain way by Medea. For, he says, she told him to lie beneath the prow of the Argo because the ship was about to fall apart because of time. When the prow fell upon him, Jason died.”
