Chapter 5: Semiramis and the Bactrian war

Diodorus’s Assyrian narrative here follows Ctesias’s Persica (Ninus and Semiramis). Ctesias does not use the name Nimrod.

[3] It was at just this time that the king, now that he had completed the founding of the city which bore his name, undertook his campaign against the Bactrians. And since he was well aware of the great number and the valour of these men, and realized that the country had many places which because of their strength could not be approached by an enemy, he enrolled a great host of soldiers from all the negotiations under his sway; for as he had come off badly in his earlier campaign, he was resolved on appearing before Bactriana with a force many times as large as theirs. [4] Accordingly, after the army had been assembled from every source, it numbered, as Ctesias has stated in his history, one million seven hundred thousand foot-soldiers, two hundred and ten thousand cavalry, and slightly less than ten thousand six hundred scythe-bearing chariots.

[5] Now at first hearing the great size of the army is incredible, but it will not seem at all impossible to any who consider the great extent of Asia and the vast numbers of the peoples who inhabit it. For if a man, disregarding the campaign of Darius against the Scythians with eight hundred thousand⁠[7] men and the crossing made by Xerxes against Greece with a host beyond number,⁠[8] should consider the events which have taken place in Europe only yesterday or the day before, he would the more quickly come to regard the statement as credible. [6] In Sicily, for instance, Dionysius led forth on his p365 campaigns from the single city of the Syracusans one hundred and twenty thousand foot-soldiers and twelve thousand cavalry, and from a single harbour four hundred warships, some of which were quadriremes and quinqueremes;⁠[9] [7] and the Romans, a little before the time of Hannibal, foreseeing the magnitude of the war, enrolled all the men in Italy who were fit for military service, both citizens and allies, and the total sum of them fell only a little short of one million; and yet as regards the number of inhabitants a man would not compare all Italy with a single one of the nations of Asia.⁠[10] Let these facts, then, be a sufficient reply on our part to those who try to estimate the populations of the nations of Asia in ancient times on the strength of inferences drawn from the desolation which at the present time prevails in its cities.
