[133] The inhabitants of Filettino probably belonged to the tribe of the Trebani, or of Trebula, who were located in the neighbourhood of Trevi, where was a Roman colony and principality. Inscriptions giving the names and titles of Augustus, Septimius Severus, and Commodus, were found here, and are published by Signor Gori in his Trattato dell’ Acqua Marcia, &c., 12mo., 1866, p. 37. Another inscription at Anagni, on the front of the Governor’s palace, gives the name of Publius Vecellius, curator of the Republic of the Trebani.
Martial mentions the Treba Augusta of Frontinus, under the name of Trebula:
“Trebula nos genuit, commendat gratia duplex Sive levi flamma, sive domamur aqua.” (Lib. v. epigr. 65, and lib. xiii. epigr. 33.)
Livy also mentions it: “Eodem anno Arpinatibus Trebulanisque civitas data.” (Livii Hist., x. 1.)
