Since those who had earlier attempted to sail around Athos had suffered shipwreck, for about three years preparations had been underway there. Triremes were anchored off Elaeus in the Chersonese; with these for their headquarters, all sorts of men in the army were compelled by whippings to dig a canal, coming by turns to the work; the inhabitants about Athos also dug. Bubares son of Megabazus and Artachaees son of Artaeus, both Persians, were the overseers of the workmen. Athos is a great and famous mountain, running out into the sea and inhabited by men. At the mountain's landward end it is in the form of a peninsula, and there is an isthmus about twelve stadia wide; here is a place of level ground or little hills, from the sea by Acanthus to the sea opposite Torone. On this isthmus which is at the end of Athos, there stands a Greek town, Sane; there are others situated seaward of Sane and landward of Athos, and the Persian now intended to make them into island and not mainland towns; they are Dion, Olophyxus, Acrothoum, Thyssus, and Cleonae.
