Roughly half way through the fourth Georgic, Virgil confronts a sad reality: on occasion the entire population of a hive can perish without warning and leave the bee-keeping farmer bee-less. In response to such a devastating loss, the poet describes an Egyptian procedure, to which modern critics have given the name bugonia, whereby the farmer acquires a new swarm of bees from the putrefying carcass of a dead ox (4.281–314). After the account of bugonia, the poem takes a notoriously unexpected turn. Virgil asks the Muses about the origins of this practice and then recounts the exploits of Aristaeus, an inhabitant of the georgic world whose own bees once succumbed to famine and disease. In the narrative that follows, Aristaeus consults his mother Cyrene and the seer Proteus, who tells him about Orpheus’ descent to the underworld. The narrative ends when Aristaeus, thanks to the teaching of his mother, performs a series of activities that culminates in a new swarm of bees bursting forth from the putrefying carcass of a dead ox (4.315–558). The aetiological character of the Aristaeus narrative is clear—Virgil promises to trace the Egyptian procedure back to its first origo (4.286), and when he addresses the Muses, he specifically asks what god discovered the practice and whence it took its first beginnings (4.315–16). But for what activity does the story actually offer an aition?
