An anonymous biography of Lucan known as the Life of Vacca attributes to the poet the composition of a work called Siluae. This information has been accepted by scholars with regard to both Lucan and Statius, thus transforming Lucan into a predecessor of Statius’ Siluae. This article seeks to demonstrate that neither the manuscript tradition of Lucan's biography nor alleged references to Lucan's Siluae in Statius’ collection substantiate the affirmation that Lucan composed a work called Siluae. It is argued that (...) the Life of Vacca is most probably late and its very long catalogue of works (mostly problematic or otherwise unknown) aggrandizes Lucan in response to the need for a commendatory biography of the poet when he became a school author. Pomponio Leto is responsible for perpetuating the mention of Lucan's Siluae by including it in his influential biography of Lucan (the first to reach the printed press). It is further argued that the circumstances of the tradition of Statius’ Siluae explain Leto's acceptance of Lucan's work of the same title. Leto was working on a commentary on the recently rediscovered Siluae, which explains his inclusion of a work called Siluae in his biography of Lucan, a great poet who had preceded Statius. Finally, this article deconstructs the theories that find references to Lucan's Siluae in Statius’ Siluae or that justify Statius’ silence about Lucan's Siluae with its political motifs. (shrink)
