A few days after this, envoys reached Alexander from the people called Abian Scythians, whom Homer commended in his poem, calling them the justest of men.[510] This nation dwells in Asia and is independent, chiefly by reason of its poverty and love of justice. Envoys also came from the Scythians of Europe, who are the largest nation dwelling in that continent.[511] Alexander sent some of the Companions with them, under the pretext indeed that they were to conclude a friendly alliance by the embassy; but the real object of the mission was rather to spy into the natural features of the Scythian land, the number of the inhabitants and their customs, as well as the armaments which they possessed for making military expeditions.[512] He formed a plan of founding a city near the river Tanais, which was to be named after himself; for the site seemed to him suitable and likely to cause the city to grow to large dimensions. He also thought it would be built in a place which would serve as a favourable basis of operations for an invasion of Scythia, if such an event should ever occur; and not only so, but it would also be a bulwark to secure the land against the incursions of the barbarians dwelling on the further side of the river. Moreover he thought that the city would become great, both by reason of the multitude of those who would join in colonizing it, and on account of the celebrity of the name conferred upon it.[513] Meantime the barbarians dwelling near the river seized upon the Macedonian soldiers who were garrisoning their cities and killed them; after which they began to strengthen the cities for their greater security. Most of the Sogdianians joined them in this revolt, being urged on to it by the men who had arrested Bessus. These men were so energetic that they even induced some of the Bactrians to join in the rebellion, either because they were afraid of Alexander, or because their seducers assigned as a reason for their revolt, that he had sent instructions to the rulers of that land to assemble for a conference at Zariaspa, the chief city; which conference, they said, would be for no good purpose.[514] CHAPTER II.
