According to Cooper, the first description of the trial given by Athenaeus and the shorter account of Pseudo-Plutarch ultimately derive from the work of the biographer Hermippus of Smyrna (c. 200 BC) who adapted the story from Idomeneus of Lampsacus (c. 300 BC). The account of Posidippus is the earliest known version. If the disrobing had happened, Posidippus would most likely have mentioned it because he was a comic poet. Therefore, it is likely that the disrobing of Phryne was a later invention, dating to some time after 290 BC, when Posidippus was active as a poet. Idomeneus was writing around that time.
