What is "tolistobogii"

Tolistobogii (in other sources Tolistobogioi, Tolistobōgioi, Tolistoboioi, Tolistobioi, Toligistobogioi or Tolistoagioi) is the name used by the Roman historian, Livy, for one of the three ancient Celtic tribes of Galatia in central Asia Minor, together with the Trocmi and Tectosages. The tribe entered Anatolia in 279 BC as a contingent of Celtic raiders from the Danube region, and settled in those regions of Phrygia which would later become part of the Roman province of Galatia. The Galatians retained their Celtic language through the 4th century AD, when Saint Jerome mentions that the Galatians still spoke a Celtic language in his times.
