Meda was the wife of Idomeneus. While her husband was away fighting in the Trojan War, Meda had intercourse with an ambitious Cretan, Leucus. Then, before the return of Idomeneus (who was king of Crete), Leucus killed Meda and her daughters, usurped the throne, and drove out Idomeneus upon his eventual return. Probably behind all this scheming and cruelty there lay medea, 'cunning', although Meda was the subject of it, not the instigator.
