Prusias ad Hypium
Prusias ad Hypium was a city in ancient Bithynia, and afterwards in the late Roman province of Honorias, and 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). Photius writes that it was called Kieros, from the river which flows by it.
Memnon of Heraclea says that King Prusias I of Bithynia (237-192 B.C.) captured from the Heracleans the town of Kieros, united it to his dominions and changed its name to Prusias. Pliny and Ptolemy merely mention it, one below Mt. Hypius, the other near the River Hypius.
Several of its bishops are known:
- George (not Hesychius, as Le Quien says), 325;
- Olympus in 451;
- Dometius in 681;
- Theophilus in 787;
- Constantine in 869;
- Leo in 879;
- St. Paul, martyred by the iconoclasts in the ninth century.
It is not known when this see disappeared; it still existed in the tenth century.

- "Frag. histor. Graec.", coll. Didot, frag. 27 and 47; fragment 41 treats of Kios/Cius or Guemlek, also called Prusias, and not of Kieros, as the copyist has written; this has given rise to numerous confusions.
