Pausanias Description of Greece 7.18.2

[2]
  About eighty stades from the river Peirus is the city of Patrae . Not far from Patrae the river Glaucus flows into the sea. The historians of ancient Patrae say that it was an aboriginal, Eumelus, who first settled in the land, and that he was king over but a few subjects. But when Triptolemus came from Attica , he received from him cultivated corn, and, learning how to found a city, named it Aroe from the tilling of the soil.

[2] About eighty stadium-lengths from the river Peiros is the city of Patrai. Not far from Patrai the river Glaukos flows into the sea. Those who memorialize [ mnēmoneuein] the-ancient-lore [ tà arkhaia] of the people-of-Patrai [ Patreîs] say that it was an aboriginal earthborn [ autokhthōn], Eumēlos, who first made-a-home [ oikeîn] in the land, and that he was-king [ basileuein] of only a few humans [ anthrōpoi]. But when Triptolemos came from Attica, he [= Eumelos] received from him [= Triptolemos] cultivated [ hēmeros] seed-for-harvesting [ karpos], and, learning how to establish [ oikizein] a city [ polis], he named it Aroē from the ploughing [ aroûn] of the land.
