The Library at Timgad was a gift to the Roman people by Julius Quintianus Flavius Rogatianus at a cost of 400,000 sesterces.Pfeiffer, H. (1931). The Roman Library at Timgad. Memoirs of the American Academy in Rome, 9, 157-165. As no additional information about this benefactor has been unearthed, the precise date of the library's construction remains uncertain. Based on the remaining archaeological evidence, it has been suggested by scholars that it dates from the late 3rd or possibly the 4th century.
