The Culex is now widely recognized as a piece of post-Ovidian, possibly Tiberian, pseudo-juvenilia written by an author impersonating the young Virgil, although it was attached to Virgil's name already in the first century c.e., being identified as Virgilian by Statius, Suetonius and Martial. Dedicated to the young Octavian (Octaui in line 1), the poem seems to fill a biographical gap in Virgil's career before his composition of the Eclogues. It is introduced as a ludus, which Irene Peirano suggests may openly refer to ‘the act of impersonating Virgil’, and, like many of the poems in the Appendix Vergiliana, it seems to have a parodic intent. The Culex has been interpreted as a parody of neoteric style and the epyllion, as mock-epic, as Virgil parody (John Henderson called it a ‘spoof Aeneid in bucolic drag’), as pointed Augustan satire, as mock Ovidian ‘Weltgedicht’ and as just very bad poetry (Housman's ‘stutterer’). Glenn Most has observed that the poem's three ‘acts’ structurally recapitulate Virgil's three major works in chronological succession. Little attention, however, has been paid to the Culex's final lines, which contain a catalogue of flowers the pastor places on the gnat's tomb. Recent scholarship has reintroduced an older interpretation of the gnat's tomb as a political allegory of Augustus’ Mausoleum; in this paper I suggest instead that the tomb and its flowers serve a closural and metapoetic function at the end of the poem.
