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.
Larisa (Troad) Larisa (Ancient Greek: Λάρισα  "Larisa" ) was an ancient Greek city in the south-west of the Troad region of Anatolia. Its surrounding territory was known in Greek as the Λαρισαῖα ("Larisaia"). It has been located on a small rise by the coast now known as Limantepe, about 3.5 km from the village of Kösedere to the north-east and 3 km from the village of Babadere to the east, in the Ayvacık district of Çanakkale province, Turkey. As with other Greek toponyms containing the consonantal string -ss-, spellings that drop one 's' exist alongside those that retain both in the ancient literary sources. Larisa in the Troad should not be confused with 'Aeolian' Larisa, near Menemen, or with 'Ionian' Larisa in İzmir province.
