The account

Herodotus tells it plainly: Mardonius sent the Persian fleet around the cape of Athos, and a savage north wind caught it on the rocks, three hundred ships gone in a night, twenty thousand men drowned or taken by the sea-monsters the sailors swore lived there. So feared was this coast that Xerxes later dug a canal through the peninsula rather than risk it again. The wrecks lie somewhere off the monks' mountain.
