Priscian

Priscianus Caesariensis (), commonly known as Priscian (ˈprɪʃən or ˈprɪʃiən), was a Latin grammarian and the author of the Institutes of Grammar, which was the standard textbook for the study of Latin during the Middle Ages. It also provided the raw material for the field of speculative grammar. The details of Priscian's life are largely unknown. Priscian was born and raised in the North-African city of Caesarea (modern Cherchell, Algeria), the capital of the Roman province of Mauretania Caesariensis, which during his lifetime would be under the control of the Vandalic Kingdom. He was probably of Greek descent. According to Cassiodorus, he taught Latin at Constantinople in the early sixth century. His minor works include a panegyric to Anastasius (491—518), written about 512, which helps establish his time period. In addition, the manuscripts of his Institutes contain a subscription to the effect that the work was copied (526, 527) by Flavius Theodorus, a clerk in the imperial secretariat. Priscian's most famous work, the Institutes of Grammar (Institutiones Grammaticae), is a systematic exposition of Latin grammar. The dedication to Julian probably indicates the consul and patrician, not the author of a well-known epitome of Justinian's Novellae, who lived somewhat later than Priscian. The grammar is divided into eighteen books, of which the first sixteen deal mainly with sounds, word-formation and inflexions; the last two, which form from a fourth to a third of the whole work, deal with syntax. Priscian's grammar is based on the earlier works of Herodian and Apollonius. The examples it includes to illustrate the rules preserve numerous fragments from Latin authors which would otherwise have been lost, including Ennius, Pacuvius, Accius, Lucilius, Cato and Varro. But the authors whom he quotes most frequently are Virgil, and, next to him, Terence, Cicero, Plautus; then Lucan, Horace, Juvenal, Sallust, Statius, Ovid, Livy and Persius.
