Abstract
The expressionpelle Libystidis ursae, which occurs atAen. 5.37 and 8.368, has caused a certain amount of puzzlement among scholars. This article will attempt to explain, through Virgil's allusions to Apollonius'Argonautica, the function ofLibystisas a pointer to the motif of the creation of a new homeland within a foreign territory, as is the case with Segesta and Rome. This idea is further developed by the two omens that forebode the foundations of Segesta and Rome, that is, the omen of Acestes' arrow atAen. 5.522–8 and the weapon-omen atAen. 8.524–9, both of which are consistently associated with flames, comets, and lightning. These elements underline the symbolism of destruction, rebirth, and Jupiter's will that characterizes the foundations of Segesta and future Rome.
