Gynaecothoenas
That is, "the god feasted by Women," a surname of Ares at Tegea. In a war of the Tegeatans against the Lacedaemonian king Charillus, the women of Tegea made an attack upon the enemy from an ambuscade. This decided the victory. The women therefore celebrated the victory alone, and excluded the men from the sacrificial feast. This, it is said, gave rise to the surname of Apollo. (Description of Greece by Pausanias viii)
