Lucius Aninius Sextius Florentinus (died between 127 and 130) was a Roman senator, who held a number of imperial appointments during the reigns of Trajan and Hadrian.
He died while governing Roman Arabia; his unnamed son had a tomb prepared for him at Petra, which still stands.
[4] Although the inscription omits any mention that Florentinus was praetor, it can be safely assumed he had, for his next three offices required that magistracy.
[4] His final posting was in Roman Arabia, where the above-mentioned papyrus attests he was in office on 2 December 127.
The next known governor of Roman Arabia, Titus Haterius Nepos, is attested as being in office 17 November 130,[8] so we can surmise that between those two dates Florentinus died of unknown causes.
