Brennus, the king of the Gauls, accompanied by one hundred and fifty thousand infantry, armed with long shields, and ten thousand cavalry, together with a horde of camp followers, large numbers of traders, and two thousand waggons, invaded Macedonia and engaged in battle. Having in this conflict lost many men … as lacking sufficient strength … when later he advanced into Greece and to the oracle at Delphi, which he wished to plunder. In the mighty battle fought there he lost tens of thousands of his comrades-in‑arms, and Brennus himself was three times wounded. Weighed down and near to death, he assembled his host there and spoke to the Gauls. He advised them to kill him and all the wounded, to burn their waggons, and to return home unburdened; he advised them also to make Cichorius king. Then, after drinking deeply of undiluted wine, Brennus slew himself. After Cichorius had given him burial, he killed the wounded and those who were victims of cold and starvation some twenty thousand in all; and so he began the journey homeward with the rest by the same route. In difficult terrain the Greeks would attack and cut off those in the rear, and carried off all their baggage. On the way to Thermopylae, food being scarce there, they abandoned twenty thousand more men. All the rest perished as they were going through the country of the Dardani, and not a single man was left to return home.
Brennus, the king of the Gauls, on entering a temple found no dedications of gold or silver, and when he came only upon images of stone and wood he laughed at them, to think that men, believing that gods have human form, should set up their images in wood and stone.
At the time of the Gallic invasion the inhabitants of Delphi, seeing that danger was at hand, asked the god if they should remove the treasures, the children, and the women from the shrine to the most strongly fortified of the neighbouring cities. The Pythia replied to the Delphians that the god commanded them to leave in place in the shrine the dedications and whatever else pertained to the adornment of the gods; for the god, and with him the White Maidens, would protect all. As there were in the sacred precinct two temples of extreme antiquity, one of Athena Pronaia and one of Artemis, they assumed that these goddesses were the “White Maidens” named in the oracle.
