Pausanias Description of Greece 1.22.6

[6] On the left of the Gateway [ Propulaia / Propylaea] is a building [ oikēma] that houses paintings [ graphai]. Among those not effaced by time there was Diomedes taking the [statue of] Athena from Troy, and Odysseus in Lemnos taking away the bow [ toxon] of Philoctetes. There in the paintings [ graphai] is Orestes killing Aigisthos, and Pylades killing the sons of Nauplios, who had come as helpers [ boēthooi] for Aigisthos. And there is Polyxena about to be slaughtered [ sphazesthai] near the tomb [ taphos] of Achilles. Homer did well in bypassing this deed, which is so raw-in-its-cruelty [ ōmon]. And I think he also did well in making [ poieîn] Achilles capture Skyros, differing entirely from those who say that Achilles had a life-experience [ diaita] in Skyros together with the maidens there, as Polygnotus has pictured-in-painting [ graphein]. He [= Polygnotus] also painted [ graphein] Odysseus happening upon the girls washing clothes with Nausikaa at the river, just like what Homer made-in-poetry [ poieîn]. There are also other paintings, including one that features Alcibiades,
