In the best MSS. the name given is always "Caelius Sedulius," and although the praenomen savours of Latin origin, and the nomen itself was not quite unknown in Rome,[34] still the name Sedulius gives decided indications of his Irish birth. At least two other distinguished Irishmen bore the same name. The first is that Sedulius of Irish origin, the Bishop of Britain, as he describes himself,[35] who subscribed the Acts of the Council of Rome held under Gregory II., in A.D. 721. The other, known as Sedulius the Younger, flourished in the first quarter of the ninth century, wrote a Commentary on St. Paul's Epistles, and, as we shall see, has been frequently confounded with his more celebrated namesake, the poet. The old form of the name in Irish was Siadhal, or Siadhel, now pronounced Shiel. But in these older forms of the language the letters were not mortified in pronunciation; and thus Sedulius is naturally the latinized form of the Irish name. From the dawn of our history it was a name celebrated in Irish literature, especially in the department of medicine. Colgan refers to eight distinguished Irishmen who bore the family name of Siadhal, amongst others to Siadhal, son of Luath, Bishop of Dubhlinn, whose death on the 12th of February, 785, is recorded in the Martyrology of Donegal. The Danes, indeed, had not arrived in Dublin so early as A.D. 785, nor is there any satisfactory evidence of a diocese of Dublin at that time. He may, however, have been an abbot in the place, with episcopal orders. The oldest writer[36] who distinctly asserts that the poet Sedulius was an Irishman is John of Tritenheim, or Trithemius, as he is more generally called.[37] This Trithemius, Benedictine abbot of Spanheim, flourished towards the end of the fifteenth century, and was certainly a very learned man. In some of the statements, however, made in this paragraph, he is not supported by any ancient authority that we know of. It is, moreover, evident from the list of the writings of Sedulius which he gives, that he confounds the poet with the commentator on St. Paul and St. Matthew, who, as all admit, was an Irishman, but flourished nearly four centuries later than the poet. Colgan, Usher, Ware, and a host of other writers at home and abroad, have followed Trithemius, and made the poet an Irishman. It is, however, certain that, although there is some evidence that he was of Irish birth, there is absolutely no evidence that he was a native of any other country. It was, indeed, said that the poet was a Spaniard, and Bishop of the Oretani, but Faustinus Arevalus, himself a Spaniard, and author of a very able dissertation on Sedulius, prefixed to his splendid edition of the _Christian Poets of the Fourth Century_, published at Rome in A.D. 1794, declares that love of truth compels him to admit that the story of his preaching at Toledo, and of his Spanish episcopacy, is fabulous.[38]
