Prusias ad Hypium (Ancient Greek: Προῦσα πρὸς τῷ Ὑππίῳ ποταμῷ)[1] was a city in ancient Bithynia, and afterwards in the late Roman province of Honorias. In the 4th century it became a bishopric that was a suffragan of Claudiopolis in Honoriade. Before its conquest by King Prusias I of Bithynia, it was named Cierus or Kieros (Ancient Greek: Κίερος) and belonged to the Heraclea Pontica.[2] Photius writes that it was called Kieros, after the river which flows by it.[3]
