But just at this time the Kelts, or Gauls, the same race who used to dwell in Britain and Gaul, made one of their great inroads from the mountains.  The Macedonians thought them mere savages, easy to conquer; but it turned out quite otherwise.  The Kelts defeated them entirely, cut off Ptolemy Keraunus’ head, and carried it about upon a pole, and overran all Thrace and Macedon.  Then they advanced to the Pass of Thermopylæ, found the way over Mount Œta by which Xerxes had surprised the Spartans, and were about to plunder Delphi, their Bran, or chief, being reported to say that the gods did not want riches as much as men did.  The Greeks, in much grief for their beloved sanctuary, assembled to fight for it, and they were aided by a terrible storm and earthquake, which dismayed the Gauls, so that the next morning they were in a dispirited state, and could not stand against the Greeks.  The Bran was wounded, and finding that the battle was lost, called the other chiefs round him, advised them to kill all the wounded men, and make their retreat as best they might, and then stabbed himself to set the example.  The others tried to retreat, but were set upon by the Greeks, tormented, and starved; and it is said that all who had marched to Delphi perished, and the only Gauls of all this host who survived were a party who had crossed the Hellespont, and made a settlement in the very heart of Asia Minor, where they were known by the name of Galatians, and still kept up their own language.
