Brennus of the Prausi lays siege to Delphi by Angus McBride

"These Gauls inhabit the most remote portion of Europe, near a great sea that is not navigable to its extremities, and possesses ebb and flow and creatures quite unlike those of other seas. Through their country flows the river Eridanus, on the bank of which the daughters of Helius (Sun) are supposed to lament the fate that befell their brother Phaethon. It was late before the name “Gauls” came into vogue; for anciently they were called Celts both amongst themselves and by others. An army of them mustered and turned towards the Ionian Sea, dispossessed the Illyrian people, all who dwelt as far as Macedonia with the Macedonians themselves, and overran Thessaly. And when they drew near to Thermopylae, the Greeks in general made no move to prevent the inroad of the barbarians, since previously they had been severely defeated by Alexander and Philip. Further, Antipater and Cassander afterwards crushed the Greeks, so that through weakness each state thought no shame of itself taking no part in the defence of the country."

-Pausanias' description of Greece 1.4.1
