Strabo, Geography

The Trocmi possess the parts near Pontus and Cappadocia. These are the most powerful of the parts occupied by the Galatians. They have three walled garrisons: Tavium, the emporium of the people in that part of the country, where are the colossal statue of Zeus in bronze and his sacred precinct, a place of refuge; and Mithridatium, which Pompey gave to Bogodiatarus, having separated it from the kingdom of Pontus; and third, Danala, where Pompey and Leucullus had their conference, Pompey coming there as successor of Leucullus in the command of the war, and Leucullus giving over to Pompey his authority and leaving the country to celebrate his triumph. The Trocmi, then, possess these parts, but the Tectosages the parts near Greater Phrygia in the neighborhood of Pessinus and Orcaorci. To the Tectosages belonged the fortress Ancyra, which bore the same name as the Phrygian town situated toward Lydia in the neighborhood of Blaudus. And the Tolistobogii border on the Bithynians and Phrygia "Epictetus" as it is called. Their fortresses are Blucium and Peïum, the former of which was the royal residence of Deïotarus and the latter the place where he kept his treasures.
