BILLAEUS
BILLAEUS (
Βιλλαῖος), a river of Bithynia, which is the modern
Filyás. [
BITHYNIA] Near the mouth of the river was the Greek town of Tios. The Billaeus is certainly a considerable stream, but the whole course does not appear to be accurately known at present.
It is mentioned by Apollonius (
2.792), and in the Periplus of Marcianus (pp. 70, 71), and by Arrian (
Peripl. p. 14).
In his list of Bithynian rivers, Pliny's text (5.32) has Lilaeus, which may be intended for Billaeus.
