Despite a large number of studies, Catullus' so-called Peleus-epic (poem 64) is still said to be enigmatic and hermetic. In a seemingly loose thematic coherence it narrates not only the nuptial of Peleus with the immortal Thetis, but also - across the different media image and song - the fate of Ariadne and the deeds of Achilles ending with a topical lament. The often criticised structure of the whole is here taken seriously as a complex, but highly artistic narrative that excells in its very own structural coherence. In particular consideration of the different narrators and different types of narration, medial aspects (ecphrastic writing, (linguistic) images) and intertextual references, this study tries to offer a new reading of the poem.
