Some tablets found in Hattusa refer to a country called Pitassa:
- The Hitttite king Arnuwanda had withdrawn its troops from the country of Pitassa and Sallapa, Madduwatta had pushed elders of Pitassa to revolt. He had faced the chariots and 200 men of the holder-scepter Zuwa, who was killed in the city of Marasa. The town was burned.
- Suppiluliuma had also faced a revolt of Pitassa associated with the city of Mahuirassa.
Mahuirassa is probably the town called Mourisa during the Greco-Roman period, not far from Ikonion, ie Konya.
The Pitassa was a frontier of the country of Tarhuntassa. Here is an excerpt of the tablet that defined its boundaries: "Towards Pitassa: Mount Hawa, the kantanna of Zarniya of the country of Hulaya, Sanantarwa (probably Sarıidris) which is in the Pitassa, and towards the district border of Pitassa, the hole of Arimmata belong to Pitassa."
The hole of Arimmata is seen as being the Lake Beysehir west of Konya. It may be the ancient name of Antioch in Pisidia:
And so the country of Pitassa, pronounced Pedassa or Pidas, was located northwest of Konya, to the Great Lakes region of Anatolia.
With a displacement of its territory further west, after the 4th century BC, the Pitassa was called Pisidia a millennium later by a reversing of the final two syllables. Ikonion was still part of Pisidia in early AD, before becoming the capital of Lykaonie in 370 AD.
