What was the name of the area in the highlands of central Anatolia ruled by Deiotarus?
Galatia Ancient Galatia ( ; Greek: Γαλατία , Turkish: "Galatlar" ) was an area in the highlands of central Anatolia (Ankara, Çorum, Yozgat Province) in modern Turkey. Galatia was named for the immigrant Gauls from Thrace (cf. Tylis), who settled here and became its ruling caste in the 3rd century BC, following the Gallic invasion of the Balkans in 279 BC. It has been called the "Gallia" of the East, Roman writers calling its inhabitants "Galli" ("Gauls" or "Celts").
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.
