Herodotus, The History of Herodotus (Rawlinson… (1910)
“ Thou art about, O king! to attack a people far superior to the Scyths, a people distinguished above others both by land and sea. 'Tis fit therefore that I should tell thee what danger thou incurrest hereby. Thou sayest that thou wilt bridge the Hellespont, and lead thy troops through Europe against Greece. Now suppose some disaster befall thee by land or sea, or by both. It may be even so; for the men are reputed valiant. Indeed one may measure their prowess from what they have already done; for when Datis and Artaphernes led their huge army against Attica, the Athenians singly defeated them. ”
