Dictionary of Greek and Roman Geography/Bryllion

BRY′LLION (Βρύλλιον: Eth. Βρυλλιανός; Steph. s. v.), a city on the Propontis in Bithynia. Stephanus reports that it was Cius, according to Ephorus, by which be probably means that Bryllium was the old name of Cius. There was a district Bryllis which contained the small town of Dascyleium. Pliny (v. 32) mentions Bryllium, which he evidently takes to be a different place from Cius, but near to it. [ G. L. ]
