In Virgil’s Eclogues the Muses Pierides are always represented as authors of the poems, like in the Gallus papyrus from Qaṣr Ibrîm. Their presence in passages allusive to the verses of the papyrus and the employ of the epithet by Prop. 2, 10 and 2, 13 in texts rich of references to Gallus suggest that the word Pierides was already in Gallus’ poetry and perhaps in the lacuna at v. 6 of the papyrus.
