Titus Caesernius Statianus

His cursus honorum up to his consulate is known from the dedication to a statue set up at Cirta in the imperial province of Numidia.[4] The first office Statianus held was in the decemviri stlitibus judicandis, one of the four boards that formed the vigintiviri; membership in one of these four boards was a preliminary and required first step toward a gaining entry into the Roman Senate. Next he was comes Augusti in Oriente, or a companion of the emperor Hadrian during his tour of the eastern provinces around the year 129.[5] His service near the emperor led to his service as quaestor as a candidate of the emperor, and upon completion of this traditional Republican magistracy Statianus would be enrolled in the Senate. He held the Republican magistracy of plebeian tribune, which was followed by the special assignment to recruit soldiers in Transpadane Italy (missus ad dilec[tu]m juniorum a Divo Hadriano in regionem Transpadanum). He then returned to Rome where he held the magistracy of praetor; Géza Alföldy dates his tenure as around the year 135.[5]

After he stepped down as praetor, Statianus was commissioned legatus or commander of Legio XIV Gemina, which at that time was stationed at Carnuntum in Pannonia Superior; Alföldy dates his service around the period from the year 136 to 138.[5] Then he was appointed the emperor's legatus in Africa. This language reflects his actual role in North Africa: his appointment made him the commander of Legio III Augusta, which was stationed at Lambaesis, which although technically made him commander of another legion, this in fact made him governor of a stretch of Roman territory adjacent to the Roman province of Africa modern scholars refer to as Numidia. Alföldy dates his tenure in Roman Numidia from around the year 138 to 141, covering the date of Hadrian's death and the succession of Antoninus Pius.[6] During that time he became the patron of the cities of Cirta and Timgad, and it was at that time a statue was erected in his honor at Cirta. Since upon holding this post a senator most often immediately acceded to the consulate, as was the case with Statianus, he was likely admitted to the Roman priesthood of the sodales Augustales prior to being sent to command the III Augusta.

Only one appointment for Statianus is known after his consulate: an inscription found at Pontailler-sur-Saone attests to his appointment as governor of Germania Superior;[7] Alföldy dates his tenure from around 149 to 152.[8] How much longer Statianus lived after returning to Rome from Germania Superior is unknown. Alföldy dates his birth around the year 105,[5] which would make him 47 when he left Germania Superior; based on what we know of Roman demographics, it is possible that Statianus lived about fifteen more years.
