There are two variations of Erigone’s myth. One version makes her the daughter of Icarius, an early king of Athens who introduced wine to Attica. When the peasants tasted the wine and became drunk for the first time, they thought that Icarius had poisoned them and therefore murdered him. Discovering his body, Erigone hanged herself in grief from the tree under which it lay.
The other version makes her the daughter of Clytemnestra and Aegisthus, who pursues Orestes to Athens seeking vengeance for their murders. When Orestes is acquitted by the Aeropagus, Erigone hangs herself in grief and anger. In this story Orestes has also killed her brother, Aletes.
"Underneath the accretions of each version lies the simple tale of a maiden whose life was cut off before she could marry. The fact that in both versions her tragedy is precipitated by the death of her father - the man who would have arranged her marriage - and in one version by the subsequent death of her brother as well - the man who would have arranged her marriage in her father’s absence - makes this point even clearer: she is alone, without anyone to guarantee her proper passage from maiden to wife".
