Kotys

Kotys was a prominent Thracian goddess who was worshipped in a festival known as the Cotyttia. She was particularly worshipped among the Edones. The Greeks considered Kotys to be an aspect of Persephone.

Kotys's followers were known as baptes, which means "bathers," because their pre-worship purification ceremony involved an elaborate bathing ritual. Kotys was often worshipped during nocturnal ceremonies, which were associated with rampant insobriety and obscene behavior, i.e. midnight orgies (orgia). Her cult was very similar to the cult of the goddess Bendis.

Etymology
The name Kotys is believed to have meant "war, slaughter", akin to Old Norse Höðr "war, slaughter".
