Aletis: Some say that she is Erigone, the daughter of Ikarios, since she wandered everywhere seeking her father. Others say she is the daughter of Aigisthos and Klytemnestra. Still others say she is the daughter of Maleotos the Tyrrhenian; others that she is Medea, since, having wandered after the murder of her children, she escaped to Aigeus. Others say that she is Persephone, wherefore those grinding the wheat offer some cakes to her.
