Sangia in the context of "Sangarios River"

The Sakarya (Turkish: Sakarya Nehri; Hittite: 𒀀𒇉𒊭𒄭𒊑𒅀, romanized: Šaḫiriya; Greek: Σαγγάριος, romanized: Sangarios; Latin: Sangarius) is the third longest river in Turkey. It runs through the region known in ancient times as Phrygia. It was considered one of the principal rivers of Asia Minor (Anatolia) in Greek classical antiquity, and is mentioned in the Iliad and in Theogony. Its name appears in different forms as Sagraphos, Sangaris, or Sagaris.

In Geographica, Strabo wrote during classical antiquity that the river had its sources on Mount Adoreus, near the town of Sangia in Phrygia, not far from the border with Galatia, and flowed in a very tortuous course: first in an eastern direction, then toward the north, then in a northwesterly direction and finally to the north through Bithynia into the Euxine (Black Sea).
