The "Contest of Cithaeron and Helicon" (PMG 654) is a fragment of a poem by Corinna. Preserved on a second-century AD papyrus discovered at Hermopolis in Egypt, the poem tells the story of a singing competition between two mountains, Cithaeron and Helicon, which was apparently won by Mount Cithaeron. Twenty-three lines of the poem are relatively well-preserved; traces of a further eleven before this section and thirty after are visible.
