Aeneas, his son Ascanius, and the prophecy of the white sow (British Museum)
cum tibi sollicito secreti ad fluminis undam
litoreis ingens inventa sub ilicibus sus
triginta capitum fetus enixa iacebit,
alba solo recubans, albi circum ubera nati,
is locus urbis erit, requies ea certa laborum.
Virgil, Aeneid, Book III, 389-393
