Dictionary of Greek and Roman Geography/Batulum
BATULUM, a town of Campania, mentioned by Virgil (Aen. vii. 739) in conjunction with Rufrae and Celenna; and by Silius Italicus (viii. 566), who associates it with Mucrae and Bovianum. The latter author clearly regards it as a Samnite city; but Virgil seems to be enumerating only places which adjoined the Campanian plain, and Servius in his note on the passage calls both Rufrae and Batulum "castella Campaniae, a Samnitibus condita." The name is not mentioned by any other author, and its site is wholly unknown.
