Pausanias Description of Greece 1.15.3

[3] At the concluding part of the painting [ graphē] are [represented] the men who fought at Marathon, namely, the men from [the city of] Plataea-in-Boeotia and the men from all the territory-of-Athens [= Attica]. They are at the moment of coming into contact in hand-to-hand combat with the barbarians. At this point, the two sides are evenly matched for the action [ ergon], but then, in a close-up of the battle [ makhē], the barbarians are starting to turn and run, heading for the marshland [ helos] and crowding each other [into the morass]. At the outer edges of the painting are [represented] the [beached] ships of the Phoenician navy and the Greeks [ Hellēnes] who are slaughtering those of the barbarians who are scrambling to climb on board. And at this point is painted [ graphesthai] also the hero [ hērōs] by the name of Marathon, after whom the plain [ pedíon] called Marathon gets its name. Also represented [ eikazesthai] is Theseus as he appeared when he was coming back up from under the earth. Also, Athena and Hēraklēs. I say-this-because [ gar], the people of Marathon were the first to establish-the-custom-of-venerating [ nomizein] Hēraklēs as a god [ theos]. Featured most prominently in the painting [ graphē] are Kallimakhos, who had been elected commander-in-chief [ polem-arkhos] by the Athenians, and Miltiades, one of the generals [ stratēgoi]. Also [featured is] a hero [ hērōs] called Ekhetlos, about whom I will make mention [ mnēmē] at a later point as well. 58
