Pausanias Description of Greece 1.32.4

[4] There is also an individual monument [ mnēma] for one man, Miltiades son of Kimon, although his end [ teleutē] happened later, after he had failed to capture Paros and for this reason had been put on trial by the Athenians. At this place [= Marathon] every night you can hear horses neighing and you can sense that men are fighting in combat. No one who has deliberately set out to experience this vision [ théā] in-full-view [ en-argēs] has ever really had any success, but still, if something is experienced in some alternative way by someone who has no ear for such things, this is no cause for anger [ orgē] on the part of the spirits [ daimones]. The people of Marathon worship [ sebesthai] both those who died in the fighting, calling them heroes [ hērōes], and also [the hero] Marathon, from whom the deme [ dēmos] derives its name, and then Hēraklēs, saying that they were the first among the Greeks [ Hellēnes] to establish-the-custom-of-thinking [ nomizein] him to be a god [ theos].
