While the Olympic Games were being celebrated, Alexander had it proclaimed in Olympia that all exiles should return to their cities, except those who had been charged with sacrilege or murder. He selected the oldest of his soldiers who were Macedonians and released them from service; there were ten thousand of these. He learned that many of them were in debt, and in a single day he paid their obligations... Diodorus Siculus, Library , 17.109.1-2

The tyrant of Athens, Pisistratus, exiled Cimon, a wealthy aristocrat, blaming him for a military and political disaster. "While in exile [Cimon] happened to take the Olympic prize in the four-horse chariot...At the next Olympic games he won with the same horses, but permitted Pisistratus to be proclaimed victor, and by resigning the victory to him he came back from exile to his own property under truce." Herodotus, Histories , 6.103.2
