References in the manuscripts are of no additional value. They tell us that he was a “Gentile layman,” or, in other words, a person not of Italian birth; that he learned philosophy in Italy; was converted and baptized by Macedonius, a presbyter; and that he wrote his theological works in Arcadia, or, as some say, Achaia. The Vatican “Codex of the Queen of Sweden” calls him a “verse-maker” and “teacher of the art of heroic metre.” Another codex adds that he also taught other varieties of metrical composition, and that all this happened in the days of the younger Theodosius, son of Arcadius, and of Valentinian, son of Constantine. Of his specific writings still another codex states that he “put forth in Achaia this book against error and composed in verse a commendation of the Christian faith.” Some Sedulius, “notable for his writings,” appears to have found his way into Spain where, in the year 428, Isicius, a Palestine monk, who had become Bishop of Toledo, detained him for his good fellowship at Toledo. With him is said to have tarried a certain Bishop Oretanus, and the inference is that these three worthies held numerous symposia upon theology and literature. But the story is denied by Nicolaus Antonius, the historian of old Spanish scholarship. Those minute and laborious investigators, the Benedictines, have, with ant-like patience, threaded every corner of the labyrinth in which these stray facts are gathered. They assert that Macedonius probably received him after he had been baptized by some one else. And while we do not know under what master he studied theology, nor even where the school was located, we know that Sedulius became presbyter in a church whose bishop’s name was Ursinus, and where Ursicinus, Laurentius, and Gallicanus were his co-presbyters. Ussher relates that the epithet _Scotigena_—the Scot—was frequently applied to him. Trithemius gives us to understand that he was led by love of learning to visit France, then Italy, then Asia, and then Achaia, and that his reputation was gained in the city of Rome. Sixtus Senensis compares him to Apollonius of Tyana in his zealous pursuit of wisdom; and enlarges the list of countries which he traversed by adding Britain and Spain. Under Theodosius and at Rome, he too declares Sedulius to have been famous in prose and verse. But Ussher first claimed him for Britain; and Ussher it was who maintained that he was a pupil of that Hildebert who ranks among the earliest of the Irish bishops. It must not be forgotten that somewhere in Britain in those days there was the light of Christianity, for in 432 St. Patrick set out from Scotland “to convert Ireland.” Nor can we omit to notice that Ussher styles Sedulius “Scotus Hybernensis,” thus originating the expression “Scotch-Irishman,” but using it in exactly the reverse of its modern sense.
