Pausanias Description of Greece 1.32.5

[5] They [= the people of Marathon] tell about something that happened at the battle [ makhē] [of Marathon]. It was the presence of a man who had the looks [ eidos] of a farmer [ agr-oikos]—and implements [ skeuē] to match. Wielding a plough [ arotron] he slaughtered with it many of the barbarians, and then, after having done what-was-done [ ergon] he disappeared [= became a-phanēs]. When the Athenians consulted the god [Apollo], he did not make-an-oracular-pronouncement [ khrēsai] with regard to him [= the man with the plough] but simply commanded them to honor [ tīmân] Ekhetlaios (= he of the plough-handle) as a hero [ hērōs]. A trophy-column [ tropaion] of white marble has been made [to mark the turning-point or tropaion of the battle of Marathon]. The Athenians say that they buried the Persians, since it is a universally [ pantōs] holy-thing [ hosion] for the corpse [ nekros] of a human to be covered by the earth, but I could not find any tomb [ taphos] for them. There was neither a tumulus [ khōma] nor any other marker [ sēmeion] to be seen. They must have carried them [= the dead Persians], just as they found them, to some ditch and tossed them in.
