The Histories · 8.120

And this also which follows is a strong witness that it was so; for Xerxes is known to have come to Abdera on his way back, and to have made with them a guest-friendship and presented them with a Persian sword of gold and a gold-spangled tiara: and as the men of Abdera themselves say (though I for my part can by no means believe it), he loosed his girdle for the first time during his flight back from Athens, considering himself to be in security. Now Abdera is situated further towards the Hellespont than the river Strymon and Eïon, from which place the story says that he embarked in the ship.
