Althaea (also commonly spelled Althea, Ancient Greek: Ἀλθαία -
Althaía) was in Greek mythology the daughter of King Thestius
and Eurythemis, and was sister to Lecla, Hypermnestra,
Iphiclus, Euippus, &c. She was also the wife of Oeneus,
king of Calydon, and mother of five sons, Meleager, Melanippe
(one of the Meleagrids), Troxeus, Thyreus, Clymenus, and two
daughters, Deianeira and Gorge. According to some writers,
Meleager was the result of a liaison with the Greek god Ares,
and Deianeira the progeny of Althaea and the god Dionysus.
Althaea is especially celebrated in ancient story about the
fate of her son Meleager, who also became the cause of her
death. When Meleager was born, the Moirae (the fates)
predicted he would only live until a brand, burning in the
family hearth, was consumed by fire. Althaea immediately hid
the brand. Later, Meleager killed his mother's two brothers in
an argument and she placed the brand back upon the fire,
killing him. Some say that she later hanged herself, others
that she killed herself with a dagger. - Wikipedia
