The Histories by Herodotus — Book VII, The greatest of armaments

For full four years after the conquest of Egypt he was equipping his force and preparing all that was needed for it; before the fifth year was completed, he set forth on his march with the might of a great multitude. ^20.2This was by far the greatest of all expeditions that we know of. The one that Darius led against the Scythians is nothing compared to it; neither is the Scythian expedition when they burst into Media in pursuit of the Cimmerians and subdued and ruled almost all the upper lands of Asia (it was for this that Darius afterwards attempted to punish them). According to the reports, the expedition led by the sons of Atreus against Troy is also nothing by comparison; neither is the one of the Mysians and Teucrians which before the Trojan war crossed the Bosporus into Europe, subdued all the Thracians, and came down to the Ionian sea, marching southward as far as the river Peneus.

^21.1All these expeditions and whatever others have happened in addition could not together be compared with this single one. For what nation did Xerxes not lead from Asia against Hellas? What water did not fail when being drunk up, except only the greatest rivers? ^21.2Some people supplied him with ships, some were enrolled in his infantry, some were assigned the provision of horsemen, others of horse-bearing transports to follow the army, and others again of warships for the bridges, or of food and ships.

^22.1Since 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. ^22.2Bubares 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. ^22.3On 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.

^23.1These are the towns situated on Athos. The foreigners dug as follows, dividing up the ground by nation: they made a straight line near the town of Sane; when the channel had been dug to some depth, some men stood at the bottom of it and dug, others took the dirt as it was dug out and delivered it to yet others that stood higher on stages, and they again to others as they received it, until they came to those that were highest; these carried it out and threw it away. ^23.2For all except the Phoenicians, the steep sides of the canal caved in, doubling their labor; since they made the span the same breadth at its mouth and at the bottom, this was bound to happen. ^23.3But the Phoenicians showed the same skill in this as in all else they do; taking in hand the portion that fell to them, they dug by making the topmost span of the canal as wide again as the canal was to be, and narrowed it as they worked lower, until at the bottom their work was of the same span as that of the others. ^23.4There is a meadow there, where they made a place for buying and marketing; much ground grain frequently came to them from Asia.

²⁴As far as I can judge by conjecture, Xerxes gave the command for this digging out of pride, wishing to display his power and leave a memorial; with no trouble they could have drawn their ships across the isthmus, yet he ordered them to dig a canal from sea to sea, wide enough to float two triremes rowed abreast. The same men who were assigned the digging were also assigned to join the banks of the river Strymon by a bridge.

^25.1Thus Xerxes did this. He assigned the Phoenicians and Egyptians to make ropes of papyrus and white flax for the bridges, and to store provisions for his army, so that neither the army nor the beasts of burden would starve on the march to Hellas. ^25.2After making inquiry, he ordered them to store it in the most fitting places, carrying it to the various places from all parts of Asia in cargo ships and transports. They brought most of it to the White Headland (as it is called) in Thrace; some were dispatched to Tyrodiza in the Perinthian country or to Doriscus, others to Eion on the Strymon or to Macedonia.
