Juliopolis, Bithnyia was founded under the Emperor Augustus by a robber chieftain named Cleon, who was a native of the region; previously it had been called Gordoucome or Gordiucome. The location of the city is unknown but it was near Nicaea.
Juliopolis, Phrygia under the name of Gordion was formerly the capital of Phrygia. It was there, in the temple of Zeus, that Alexander cut the famous Gordian knot. Its ruins are about six miles S.S.E. of Nali-Khan, and about three miles north of the Sangarius, in the plain of Aimanghir and the vilayet of Angora.
