The Scythians themselves have no cities; but there are great rivers in Scythia, whereof the Ister is the greatest of all known streams, being greater even than the Nile, if we reckon its tributaries. The great god of the Scythians is Ares; and their war customs are savage exceedingly, and all their ways barbarous. Against this folk Darius resolved to march. His plan was to convey his army across the Bosphorus on a bridge of boats, while the Ionian fleet should sail up to the Ister and bridge that, and await him. So he crossed the Bosphorus and marched through Thrace, subduing on his way the Getse, who believe that there is no true death. But when he passed the Ister, he would have taken the Ionians along with him; but by counsel of Coes of Mitylene, he resolved to leave them in charge of the bridge, giving order that, after sixty days, they might depart home, but no sooner. Then the Scythians, fearing that they could not match the great king's army, summoned the other barbaric peoples to their aid; among whom were the Sauromatians, who are fabled to be the offspring of the Amazons. And some were willing, but others not. Therefore the Scythians retired before Darius, first towards those peoples who would not come to their help; and so enticed him into desert regions, yet would in no wise come to battle with him. Now, at length, Darius found himself in so evil a plight that he began to march back to the Ister. And certain Scythians came to the Ionians, and counselled them to destroy the bridge, the sixty days being passed. And this Miltiades, the Athenian despot of the Chersonese, would have had them do, so that Darius might perish with all his army; but Histiæus of Miletus dissuaded them, because the rule of the despots was upheld by Darius. And thus the Persian army was saved, Megabazus being left in Europe to subdue the Hellespontines. When Megabazus had subdued many of the Thracian peoples, who, indeed, lack only union with each other to make them the mightiest of all nations, he sent an embassy to Amyntas, the king of Macedon, to demand earth and water. But because those envoys insulted the ladies of the court, Alexander, the son of Amyntas, slew them all, and of them or all their train was never aught heard more. Now Darius, with fair words, bade Histiseus of Miletus abide with him at the royal town of Susa. Then Aristagoras, the brother of Histiæus, having failed in an attempt to subdue Naxos, and fearing both Artaphernes, the satrap of Sardis, and the Persian general Megabazus, with whom he had quarrelled, sought to stir up a revolt of the Ionian cities; being incited thereto by secret messages from Histiseus.
