This volume is the first dedicated English commentary on the eighth and final book of Valerius Flaccus' Flavian epic Argonautica. The commentary addresses questions of the original length of the poem, of intertextuality, and of poetic practices in late first-century CE Rome. Castelletti's commentary on Book 8 of Valerius' Argonautica is an indispensable contribution to Valerian studies, whose particular strengths lie in its engagement with the literary aspects of the poem.
