Zonaras discusses the history of Lavinium, the founding of Alba Longa, and the naming of the Tiber:
After some time had passed and the Latins had increased the population of Lavinium, most of them left the city and founded another one in a more agreeable region, which they called Alba Longa – Alba because of its whiteness, and Longa because of its magnitude. Upon the death of Ascanius, the Latins honored the son born to Aeneas from Lavinia (named Silvius) over and above the son of Ascanius, preferring Silvius because Latinus was his grandfather. An Aeneas was born to Silvius, from this Aeneas was born another Latinus, and Pastis succeeded this Latinus. A man named Tiberinus, setting out on the river named Albulus, fell in and died. This river was afterward called the Tiber after him; it flowed through Rome, provided a most excellent supply to the city, and was useful to the Romans in the highest degree. Amulius, the son of Tiberinus, who became exceedingly arrogant and attempted to deify himself, died while trying to return lightning against lightning by means of a contrivance, and even to make the light flash and hurl thunderbolts. The pond near which his palace was built suddenly began to flow and swept both Amulius and his palace into the sea. Then, Amulius’ son Aventinus was killed in battle.
7.1. (Pt. 2) Χρόνου δὲ διεληλυθότος πληθυνθέντες οἱ Λατῖνοι τὴν μὲν πόλιν τὸ Λαουίνιον οἱ πλείονες ἐκλελοίπασιν, ἑτέραν δ’ ἐν ἀμείνονι χώρᾳ ἀντῳκοδόμησαν, ἣν ῎Αλβαν ἐκ τῆς λευκότητος καὶ ἀπὸ τοῦ μήκους Λόγγαν ἐπωνόμασαν· εἴποιεν ἂν ῞Ελληνες λευκὴν καὶ μακράν. ᾿Ασκανίου δὲ τελευτήσαντος οἱ Λατῖνοι τὸν ἐκ τῆς Λαουινίας τεχθέντα τῷ Αἰνείᾳ υἱὸν εἰς τὴν βασιλείαν προετιμήσαντο τοῦ ᾿Ασκανίου παιδός, διὰ τὸν πάππον τὸν Λατῖνον τοῦτον προκρίναντες, Σιλούιον κεκλημένον. ἐκ Σιλουίου δὲ Αἰνείας ἐτέχθη, ἐξ Αἰνείου δὲ Λατῖνος ἐγένετο, Λατῖνον δὲ διεδέξατο Πάστις. Τιβερῖνος δ’ ἄρξας μετέπειτα ἐν ποταμῷ καλουμένῳ ᾿Αλβούλῳ πεσὼν διεφθάρη· ὃς δὴ ποταμὸς Τίβερις ἐξ ἐκείνου μετωνομάσθη, ῥέων διὰ τῆς ῾Ρώμης καὶ ὢν τῇ πόλει πολυαρκέστατος καὶ ῾Ρωμαίοις ἐς τὰ μάλιστα χρησιμώτατος. ἔκγονος δὲ τοῦ Τιβερίνου ᾿Αμούλιος, ὃς ὑπερφρονήσας καὶ θεοῦν ἑαυτὸν τολμήσας, ὡς βροντάς τε ταῖς βρονταῖς ἐκ μηχανῆς ἀντεπάγειν καὶ ἀνταστράπτειν ταῖς ἀστραπαῖς ἐνσκήπτειν τε κεραυνούς, διεφθάρη, τῆς λίμνης παρ’ ᾗ τὰ αὐτοῦ βασίλεια ἵδρυτο ἐπιρρυείσης αἰφνίδιον καὶ καταποντισάσης κἀκεῖνον καὶ τὰ βασίλεια. ᾿Αουεντῖνος δὲ ὁ υἱὸς αὐτοῦ ἐν πολέμῳ ἀπέθανε.
