Baptae
From BiblePortal Wikipedia
Baptae [1]
(from Βάπτω , To Wash ) , a name formerly applied to the priests of the Thracian goddess Cotys, or Cotytto, and was derived from a practice in their festivals of washing in tepid water. Buttmann, however, in his Mythologus denies that the name Baptae was applied to the priests referred to. (See Cotys).
