John Bostock translation
Paphlagonia was bounded by Bithynia on the west, and by Pontus on the east, being separated from the last by the river Halys; on the south it was divided by the chain of Mount Olympus from Phrygia in the earlier times, from Galatia at a later period; and on the north it bordered on the Euxine.
