CERBALUS a river of Apulia, mentioned only by Pliny (Plin. Nat. 3.11. s. 16), who makes it the northern boundary of the Daunians. It is now called the Cervaro, a considerable stream, which rises in the Apennines on the confines of Samnium, near Ariano, flows by Bovino(Vibinum), and after traversing the plain of Apulia, receives the waters of the Candelarojust before it enters the Adriatic near Sipontum. Procopius ( B. G. 3.18) speaks of a place called Cervarium (Κερβάριον) in Apulia, which derived its name from this river.
