Festivals feature prominently in Latin literature, even in works that are not explicitly dedicated to festive days like Ovid's Fasti. _Festivals in Latin Literature_ explores the role of festivals in elegiac, lyric, and epic poetry, as well as historiography. In all of these, festivals play a more pervasive role than has so far been realised. Tibullus' elegiac oeuvre rests on an interplay between amatory and festive poetics that even has a political meaning to it, and Propertius uses festivals in his fourth book of elegies to question, from an amatory perspective, the memory typically associated with some key Roman festivals. In the poetry of Sulpicia and Ovid's _Tristia_, festivals allow voices that are otherwise marginalised to shape their own fame and commemoration. Horace's _Odes_ and the _Carmen saeculare_ rest on an intriguing interplay of festivity in the private sphere, which forms but a fleeting and precious moment, and the monumentality of public festivals, in which the poet styles himself as a master of Roman time. Post-Vergilian Latin epicists use festivals to explore the fragility of human identity in a world dominated by the gods, in Ovid's _Metamorphoses_, and to question further the commemoration connected with festive days. In particular, Statius in his _Thebaid_ undermines the foundational importance of festivals in the Aeneid, vividly staging the problematic meaning of festivals that convey a premature commemoration of an epic conflict that is unspeakable (_nefas_). Finally, in _Livy's ab urbe condita_ and _Tacitus' Histories_, festivals both provide structure and capture long-term developments in Roman history, including Rome's rise to power and the collapse of its morals, while situating both works in broader historiographical and intertextual dialogues. The book sheds new light on these authors and works, uncovering their unique 'festive poetics'. It demonstrates that Latin literature adds important new aspects to our general understanding of festivals, which, as seen throughout the book, offer even richer avenues of creating meaning and shaping or questioning commemoration than is often assumed.
