1Medemi lacus, Lake of Medea’s laughter.
Jason's success was due in large part to the help of Medea, the daughter of King Aeëtes, who had fallen in love with him.
Medea was a powerful sorceress and provided Jason with a magical ointment to protect him from the bulls' fire and a potion to lull the dragon to sleep.
Medea then used her sorcery to trick Pelias' daughters into killing their father, believing they were making him young again.
Jason did not take the throne of Iolcus; instead, he and Medea fled to Corinth, where their story would take a darker turn, ultimately leading to Jason's tragic end.
Medea brings him down as the Argonauts approach.
