What was the name of the area in the highlands of central Anatolia ruled by Deiotarus?
Deiotarus Deiotarus of Galatia (in Galatian and Greek Deiotaros, surnamed Philoromaios;  105 BC 42 BC, 41 BC or 40 BC) was a Chief Tetrarch of the Tolistobogii in western Galatia, Asia Minor, and a King of Galatia ("Gallo-Graecia"). He was considered one of the most adept of Celtic kings, ruling the three tribes of Celtic Galatia from his fortress in Blucium.
Marhasi Marhaši ("Mar-ḫa-ši" , "Marhashi", "Marhasi", "Parhasi", "Barhasi"; in earlier sources Waraḫše) was a 3rd millennium BC polity situated east of Elam, on the Iranian plateau. It is known from Mesopotamian sources, but its precise location has not been identified, though some scholars link it with Jiroft. An inscription attributed to Lugal-Anne-Mundu of Adab (albeit in much later copies) mentions it among the seven provinces of his empire, between the names of Elam and Gutium. This inscription also recorded that he confronted their governor (ensi), Migir-Enlil of Marhashi, who had led a coalition of 13 rebel chiefs against him.
