Cornutus was a native of Leptis Magna in Libya, but resided for the most part in Rome. He is best known as the teacher and friend of Persius, whose fifth satire is addressed to him, as well as other distinguished students, such as Claudius Agathemerus. "Through Cornutus Persius was introduced to Annaeus, as well as to Lucan, who was of his own age, and also a disciple of Cornutus". At Persius's death, Cornutus returned to Persius' sisters a bequest made to him, but accepted Persius' library of some 700 scrolls. He revised the deceased poet's satires for publication, but handed them over to Caesius Bassus to edit, at the special request of the latter. Among Persius's satires were lines that, as Suetonius records, "even lashed Nero himself, who was then the reigning prince. The verse ran as follows: but Cornutus altered it to: in order that it might not be supposed that it was meant to apply to Nero." Annaeus Cornutus was banished by Nero nevertheless — in 66 or 68 AD — for having indirectly disparaged the emperor's projected history of the Romans in heroic verse, after which time nothing more is heard of him.
Writings
He was the author of various rhetorical works in both Greek and Latin, such as De figuris sententiarum. Excerpts from his treatise De enuntiatione vel orthographia are preserved in Cassiodorus. A commentary on Virgil is frequently quoted by Servius, but tragedies mentioned by Suetonius have not survived. Cornutus wrote a work on Rhetoric, and a commentary on the Categories of Aristotle, whose philosophy he attacked along with his fellow Stoic Athenodorus. He also wrote a work called On Properties.
''Compendium of Greek Theology''
His one major surviving work, the philosophical treatise, Theologiae Graecae compendium is a manual of "popular mythology as expounded in the etymological and symbolical interpretations of the Stoics". This early example of a Roman educational treatise, provided an account of Greek mythology on the bases of highly elaborated etymological readings. Cornutus sought to recover the earliest beliefs that primitive people had about the world by examining the various names and titles of the gods. The result, to modern eyes, is often bizarre, with many forced etymologies, as can be seen from the opening paragraph, where Cornutus describes Heaven :
The Heaven , my boy, encompasses round aboutthe earth and the sea and everything both on the earth and the sea. On this account it has acquired its appellation, since it is an "upper limit" of all things and "marks of the bounds" of nature. Some say, however, that it is called Heaven from its "looking after" or "tending to" things, that is, from its guarding them, from which also "doorkeeper" and "watching carefully" are named. Still others derive its etymology from its "being seen above" . Together with everything it encompasses, it is called the "world" from its being "so beautifully ordered"
The book continues in a similar vein, proceeding from such gods as Zeus, Hera, Cronus, and Poseidon, to the Furies, Fates, Muses, and Graces. The work is pervaded throughout with a strong undercurrent of Stoic Physics. We are told that the world has a soul that preserves it called Zeus who dwells in Heaven whose substance is fiery. Zeus is the power that pervades everything, and who assigns Fate to each person. The gods have sent us Reason, which does not work evil, but which is part of the divine Reason of the universe:
"Ocean" is the Logos that "glides swiftly" and changes continuously, whereas Tethys is the stability of the qualities. For from their blending or mixing come about those things that exist; and nothing would exist if either one unmixed gained the upper hand over the other.
Spurious works
Scholia to Persius are also attributed to Annaeus Cornutus; the latter, however, are of much later date, and are assigned by Jahn to the Carolingian period. The so-called Disticha Cornuti belong to the Late Middle Ages. In 1891, Johannes Graeven proposed that an anonymous rhetorical treatise written in the 3rd century was written by a Cornutus. This attribution has not been generally accepted and, in any case, would refer to a later Cornutus.
