After a period of neglect, Ovid's elegiac poem on the Roman calendar has been the focus of much recent scholarship. In her comprehensive and scholarly study of the final book, Joy Littlewood analyses Ovid's account of the origins of the festivals of June, demonstrating that Book 6 is effectively a commemoration of Roman War, and elegantly provides a framing bracket to balance the opening celebration of Peace in Book 1. She explores the subtle interweaving of pietas and virtus in Roman religion and its relationship to Augustan ideology, the depth and accuracy of Ovid's antiquarianism, and his audacious expansion of generic boundaries.
