The Histories by Herodotus — Book IV, Darius bridges the Bosporus

While Darius was making preparations against the Scythians, and sending messengers to direct some to furnish infantry and some to furnish ships, and others again to bridge the Thracian Bosporus, Artabanus, son of Hystaspes and Darius' brother, by no means wanted him to make an expedition against the Scythians, telling him how hard that people were to deal with. ^83.2But when, for all his good advice, he could not deter the king, Artabanus ceased to advise, and Darius, all his preparations made, led his army from Susa.

^84.1Then the Persian Oeobazus, who had three sons, all with the army, asked Darius that one be left behind. “You are my friend,” said the king, “and your request is reasonable; I will leave all your sons.” ^84.2Oeobazus was very happy, supposing his sons released from service; but Darius told those whose job it was to execute all of Oeobazus' sons. So their throats were cut, and they were left there.

^85.1But Darius, when he came to that place in his march from Susa where the Bosporus was bridged in the territory of Calchedon, went aboard ship and sailed to the Dark Rocks (as they are called), which the Greeks say formerly moved; there, he sat on a headland and viewed the Pontus, a marvellous sight. ^85.2For it is the most wonderful sea of all. Its length is eleven thousand one hundred stades, and its breadth three thousand three hundred stades at the place where it is widest. ^85.3The channel at the entrance of this sea is four stades across; the narrow neck of the channel, called Bosporus, across which the bridge was thrown, is about one hundred and twenty stades long. The Bosporus reaches as far as to the Propontis; ^85.4and the Propontis is five hundred stades wide and one thousand four hundred long; its outlet is the Hellespont, which is no wider than seven stades and four hundred long. The Hellespont empties into a gulf of the sea which we call Aegean.

^86.1These measurements have been made in this way: a ship will generally accomplish seventy thousand orguiae in a long day's voyage, and sixty thousand by night. ^86.2This being granted, seeing that from the Pontus' mouth to the Phasis (which is the greatest length of the sea) it is a voyage of nine days and eight nights, the length of it will be one million one hundred and ten thousand orguiai, which make eleven thousand stades. ^86.3From the Sindic region to Themiscura on the Thermodon river (the greatest width of the Pontus) it is a voyage of three days and two nights; that is, of three hundred and thirty thousand orguiai, or three thousand three hundred stades. ^86.4Thus have I measured the Pontus and the Bosporus and Hellespont, and they are as I have said. Furthermore, a lake is seen issuing into the Pontus and not much smaller than the sea itself; it is called the Maeetian lake, and the mother of the Pontus.

^87.1After having viewed the Pontus, Darius sailed back to the bridge, whose architect was Mandrocles of Samos; and when he had viewed the Bosporus also, he set up two pillars of white marble by it, engraving on the one in Assyrian and on the other in Greek characters the names of all the nations that were in his army: all the nations subject to him. The full census of these, over and above the fleet, was seven hundred thousand men, including horsemen, and the number of ships assembled was six hundred. ^87.2These pillars were afterward carried by the Byzantines into their city and there used to build the altar of Orthosian Artemis, except for one column covered with Assyrian writing that was left beside the temple of Dionysus at Byzantium. Now if my reckoning is correct, the place where king Darius bridged the Bosporus was midway between Byzantium and the temple at the entrance of the sea.

^88.1After this, being pleased with his bridge of boats, Darius made a gift of ten of everything to Mandrocles the Samian, the architect of it; Mandrocles took the first-fruits of these and had a picture made with them, showing the whole bridge of the Bosporus, and Darius sitting aloft on his throne and his army crossing; he set this up in the temple of Hera, with this inscription: ^88.2“After bridging the Bosporus that teems with fish,
Mandrocles dedicated a memorial of the floating bridge to Hera,
Having won a crown for himself, and fame for the Samians,
Doing the will of King Darius.” This memorialized the builder of the bridge.

^89.1Darius, after rewarding Mandrocles, crossed over to Europe; he had told the Ionians to sail into the Pontus as far as the Ister river, and when they got to the Ister, to wait there for him, bridging the river meanwhile; for the fleet was led by Ionians and Aeolians and men of the Hellespont. ^89.2So the fleet passed between the Dark Rocks and sailed straight for the Ister and, after a two days' voyage up the river from the sea, set about bridging the narrow channel of the river where its various mouths separate. ^89.3But Darius, passing over the Bosporus on the floating bridge of ships, journeyed through Thrace to the sources of the Tearus river, where he camped for three days.

^90.1The Tearus is said by those living on it to be the best river of all for purposes of healing, especially for healing mange in men and horses. Its springs are thirty-eight in number, some cold and some hot, all flowing from the same rock. ^90.2There are two roads to the place, one from the town of Heraeum near Perinthus, one from Apollonia on the Euxine sea; each is a two days' journey. This Tearus is a tributary of the Contadesdus river, and that of the Agrianes, and that of the Hebrus, which empties into the sea near the city of Aenus.

^91.1Having come to this river and camped there, then, Darius was pleased with the sight of it, and set up yet another pillar there, cut with this inscription: ^91.2“From the headwaters of the river Tearus flows the best and finest water of all; and to them came, leading an army against the Scythians, the best and finest man of all, Darius son of Hystaspes, king of Persia and all the continent.” Such was the inscription.

⁹²From there, Darius set out and came to another river called Artescus, which flows through the country of the Odrysae; and having reached this river, he pointed out a spot to the army, and told every man to lay one stone as he passed in this spot that he pointed out. After his army did this, he led it away, leaving behind there great piles of stones.

⁹³But before he came to the Ister, he first took the Getae, who pretend to be immortal. The Thracians of Salmydessus and of the country above the towns of Apollonia and Mesambria, who are called Cyrmianae and Nipsaei, surrendered without a fight to Darius; but the Getae resisted stubbornly, and were enslaved at once, the bravest and most just Thracians of all.

^94.1Their belief in their immortality is as follows: they believe that they do not die, but that one who perishes goes to the deity Salmoxis, or Gebeleïzis, as some of them call him. ^94.2Once every five years they choose one of their people by lot and send him as a messenger to Salmoxis, with instructions to report their needs; and this is how they send him: three lances are held by designated men; others seize the messenger to Salmoxis by his hands and feet, and swing and toss him up on to the spear-points. ^94.3If he is killed by the toss, they believe that the god regards them with favor; but if he is not killed, they blame the messenger himself, considering him a bad man, and send another messenger in place of him. It is while the man still lives that they give him the message. ^94.4Furthermore, when there is thunder and lightning these same Thracians shoot arrows skyward as a threat to the god, believing in no other god but their own.

^95.1I understand from the Greeks who live beside the Hellespont and Pontus, that this Salmoxis was a man who was once a slave in Samos, his master being Pythagoras son of Mnesarchus; ^95.2then, after being freed and gaining great wealth, he returned to his own country. Now the Thracians were a poor and backward people, but this Salmoxis knew Ionian ways and a more advanced way of life than the Thracian; for he had consorted with Greeks, and moreover with one of the greatest Greek teachers, Pythagoras; ^95.3therefore he made a hall, where he entertained and fed the leaders among his countrymen, and taught them that neither he nor his guests nor any of their descendants would ever die, but that they would go to a place where they would live forever and have all good things. ^95.4While he was doing as I have said and teaching this doctrine, he was meanwhile making an underground chamber. When this was finished, he vanished from the sight of the Thracians, and went down into the underground chamber, where he lived for three years, ^95.5while the Thracians wished him back and mourned him for dead; then in the fourth year he appeared to the Thracians, and thus they came to believe what Salmoxis had told them. Such is the Greek story about him.

^96.1Now I neither disbelieve nor entirely believe the tale about Salmoxis and his underground chamber; but I think that he lived many years before Pythagoras; ^96.2and as to whether there was a man called Salmoxis or this is some deity native to the Getae, let the question be dismissed.

^97.1Such were the ways of the Getae, who were subdued by the Persians and followed their army. When Darius and the land army with him had come to the Ister, and all had crossed, he had the Ionians break the bridge and follow him in his march across the mainland, together with the men of the fleet. ^97.2So the Ionians were preparing to break the bridge and do Darius' bidding; but Cöes son of Erxander, the general of the Mytilenaeans, after first asking if Darius were willing to listen to advice from one who wanted to give it, said, ^97.3“Since, O King, you are about to march against a country where you will not find tilled lands or inhabited cities, let this bridge stay where it is, leaving those who made it to guard it. ^97.4Thus, if we find the Scythians and do what we want, we have a way of return; and even if we do not find them, at least our way back is safe; for my fear has never been that we shall be overcome by the Scythians in the field, but rather that we may not be able to find them, and so go astray to our harm. ^97.5Now it may perhaps be said that I say this for my own sake, because I want to remain behind; but it is not so; I only declare publicly the opinion that I think best for you, and I will follow you and do not want to be left here.” ^97.6Darius was very pleased with this advice, and he answered Cöes thus: “My friend from Lesbos, do not fail to show yourself to me when I return to my house safe, so that I may make you a good return for your good advice.”

^98.1After saying this, he tied sixty knots in a thong, and summoning the Ionian sovereigns to an audience said to them: ^98.2“Gentlemen of Ionia, I take back the decision which I delivered before about the bridge; now, take this thong and do as follows. Begin to reckon from the day when you see me march away against the Scythians, and untie one knot each day: and if the days marked by the knots have all passed and I have not returned, embark for your own homes. ^98.3But until then, since the plan is changed, guard the bridge, making every effort to keep and watch it. You will please me very much if you do this.” Having said this, Darius hastened to march further.
