Book 10
2.2
As they were disheartened at the greatness of the fine, Philomelus, son of Theotimus, than whom no Phocian stood higher in rank, his country being Ledon, a city of Phocis, took charge and tried to persuade them to seize the sanctuary at Delphi, pointing out that the amount of the sum to be paid was beyond their resources. He stated, among other plausible arguments, that Athens and Sparta had always been favorable to them, and that if Thebes or any other state made war against them, they would have the better owing to their courage and resources.
2.3
When Philomelus put all this before them, the Phocians were nothing loath, either because their judgment was blinded by heaven, or because their nature was to put gain before religion. The seizure of Delphi by the Phocians occurred when Heracleides was president at Delphi and Agathocles archon at Athens, in the fourth year of the hundred and fifth Olympiad,357 B.C when Prorus of Cyrene was victorious in the foot-race.
