Priscillian

Priscillian is a rare name, both in terms of how little it is used in current times and that it is a masculinization of the Biblical names Prisca and Priscilla. Borne by a 4th century Bishop in Ávila, Spain, notable for creating Priscillianism, a sect of Christianity which was later rejected as heresy by the Eastern Orthodox and the Roman Catholic Churches.

Priscillus and Priscillianus are other masculine forms of the ancient name.

Pronounced pris-SIL-ee-uhn.
