(Κάβαρνος), a mythical personage of the island of Paros, who revealed to Demeter the fact of her daughter having been carried off, and from whom the island of Paros was said to have been called Cabarnis. (Steph. Byz. s. v. Πάρος.) From Hesychius (s. v. Κάβαρνοι) it would seem that, in Paros, Cabarnus was the name for any priest of Demeter.
