Ovid reports a legend that identifies Anna Perenna with the sister of Dido, the Carthaginian founder in Virgil's "Aeneid". After Dido's tragic death, Anna finds refuge from her brother Pygmalion on Malta, with Battus, the king of the island and a wealthy host. Upon protecting Anna for three years, Battus counselled her to flee for her safety and find a fresh place of exile as her brother was seeking war. Forced again to flee over the seas, Anna Perenna was shipwrecked on the coasts of Latium where she was hosted by Aeneas' settlement of Lavinium. Anna's presence there made Lavinia increasingly jealous. Dido appeared in Anna's dream, exhorting her to abandon her latest refuge, from where she was swept away by the river Numicus and transformed into a river nymph hidden in the "perennial stream" ("amnis perennis"), and renamed Anna Perenna.
