Celts, the Celtic people the original inhabitants of Galacia,
Seeing something of a Hellenized savage in the Galatians, Francis Bacon and other Renaissance writers called them "Gallo-Graeci", "Gauls settled among the Greeks" and the country "Gallo-Graecia", as had the 3rd century AD Latin historian Justin.The more usual term in Antiquity is Ἑλληνογαλάται (Hellēnogalátai) of Diodorus Siculus' Biblioteca historica v.32.5, in a passage that is translated "...and were called Gallo-Graeci because of their connection with the Greeks", identifying Galatia in the Greek East as opposed to Gallia in the West.
The Galatians were in their origin a part of the great Celtic migration which invaded Macedon, led by Brennus. The original Celts who settled in Galatia came through Thrace under the leadership of Leotarios and Leonnorios circa 270 BC. Three tribes comprised these Celts, the Tectosages, the Trocmii, and the Tolistobogii.
