PRISCIANUS, one of the most celebrated of the ancient grammarians, was surnamed Cæsariensis, either because he was born at Cæsarea, or had received his education there. He flourished in the reign of Justin about the middle of the fifth century, and taught grammar at Constantinople, where he received a salary from the court, which makes it probable that he was a Christian. He has left Commentariorum Grammaticorum libri xviii. ad Julianum, besides eleven smaller pieces. His grammatical works have been published by Krehl, Leipzig, 1819, in 2 vols.; and his smaller essays by Lindemann, Leyden, 1817.
