Нума Помпилий
Numa Pompilius died in 673 BC of old age. According to Ovid's "Metamorphoses", with Numa's death Egeria melted into tears of sorrow, thus becoming a spring ("...donec pietate dolentis / mota soror Phoebi gelidum de corpore fontem / fecit..." ), traditionally identified with the one nearby Porta Capena in Rome.
