This chapter presents a reading of Propertius 3.12. The chapter argues that Propertius uses the centre of Book 3 (3.12 is the first poem of the Book’s second half) to present a rearticulation of elegy’s puella. In one sense, the poem presents its central female character as the antithesis of Propertius’s own Cynthia: Galla in 3.12 is married and faithful, and the poem’s celebration of traditional morality continues the inclusion of ‘Augustan’ themes in the Book’s central sequence. In other sense, the poem foregrounds the qualities elegy had always desired of its puella: Galla proves not the antithesis of Cynthia but an idealised Cynthia instead. Furthermore, an intertextual dialogue with Horace Odes 3.7 (the ‘Asterie’ ode) furthers competition between lyric and elegy for ownership of the theme of erotic fides (‘good faith’).
