In his carmen 63, Catullus describes the transformation of a young Greek man, Attis, into a sexually ambivalent disciple of the goddess Cybele. The ensuing instability of gender identity expressed in the poem by a mixture of feminine and masculine forms has been a source of confusion for textual critics and translators alike, resulting in conjectures and translations that render the text more binary and therefore easier to grasp. In current times, where the assumption of sexual dichotomy is challenged both by science and by society, a fresh look at the manuscripts’ original versions may encourage fruitful discussions and a new relevance to the poem in today’s classroom.
