Note 62 — Chapter XXXVIII · FROM THE BATTLE OF MARATHON TO THE MARCH OF XERXES AGAINST GREECE.
Reading edition
Æschylus, Pers. 14-124, 722-737. Heeren (in his learned work on the commerce of the ancient world, Über den Verkehr der alten Welt, part 1, sect. 1, pp. 162, 558, 3d edition) thinks that Herodotus had seen the actual muster-roll, made by Persian authority, of the army at Doriskus. I cannot think this at all probable: it is much more reasonable to believe that all his information was derived from Greeks who had accompanied the expedition. He must have seen and conversed with many such. The Persian royal scribes, or secretaries, accompanied the king, and took note of any particular fact or person who might happen to strike his attention (Herodot. vii, 100; viii, 90), or to exhibit remarkable courage. They seem to have been specially attached to the person of the king as ministers to his curiosity and amusement, rather than keepers of authentic and continuous records.
Heeren is disposed to accept the numerical totals, given by Herodotus as to the army of Xerxes, much too easily, in my judgment: nor is he correct in supposing that the contingents of the Persian army marched with their wives and families (pp. 557-559).
