Alba Longa, on the *Albanus mons, near modern Castel Gandolfo, traditionally founded c.1152 bce by *Ascanius (Aen. 3. 390 f.), and supposed founder of other Latin cities. There are rich cemeteries of the Latian culture, extending back to the 10th cent. bce. Apparently it once headed a league (of Prisci Latini? see Festus 253 Lindsay), the nature and members of which cannot be exactly determined: lists in Diodorus Siculus (7. 5), Dionysius (Ant. Rom. 4. Rom. 92, 5. 61), and Pliny (HN 3. 69), like surviving lists of Alban kings, are untrustworthy. Alba lost its primacy in Latium perhaps in the 7th cent. bce, allegedly through its destruction by Rome: some families are said to have migrated to Rome (Iulii, Tullii, etc. : Livy 1. 29 f.; Tac. Ann. 11. 24), while others joined neighbouring *Bovillae and preserved Alban cults and memorials until late times (Albani Longani Bovillenses: ILS 6188 f.
