Gaius Plinius Secundus, HN  35.132 (ca. A.D. 65): Fecit et grandes picturas, in quibus sunt Calypso et Io et Andromeda; Alexander quoque in Pompei porticibus praecellens et Calypso sedens huic eidem adscribuntur. He [Nicias the Athenian] also executed some large pictures, among them a Calypso, an Io, and an Andromeda; and also the very fine Alexander in the Porticoes of Pompeius and a seated Calypso are assigned to him.
