Pausanias Description of Greece 1.32.7

[7] There is at Marathon a lake [ limnē] which for the most part is marshy [ hel-ōdēs]. Into this lake fell the barbarians [= the Persians] as they were turning and running [after the battle], since they did not know their way around the roads, and it is said that much of the slaughter [ phonos] that followed was because of this. Above the lake are the stone stables of the horses of Artaphernes, and there are marks [ sēmeia] of his tent [ skēnē] on the rocks. Out of the lake flows a river, providing near the lake itself water suitable for cattle, but near its mouth it becomes saline and full of sea fish. A little beyond the plain is the Hill of Pan and a Cave of Pan, which is worthy of viewing [ théā]. The entrance to it is narrow, but farther in are chambers and baths and the so-called Pan’s herd of goats, which are rocks that look very much like goats.
