Among the other additions which Nennius, pupil of Elbodug, Bishop of Bangor,[330] made to the _Historia Brittonum_, was a sketch of the life of St. Patrick (caps. 50-55). It is to be observed that in another interpolation concerning the migrations of the Scotti (c. 15) Nennius refers to oral information which he received from Irish scholars (_sic mihi peritissimi Scottorum nuntiauerunt_), and it is possible that for the Patrician section also he may have received help from the same source. (1) The account of the mission of Palladius, the ordination of Patrick, and his departure for Ireland, is derived directly from Muirchu, but with some additions.[331] (2) The description of Patrick’s experience on “Cruachan Eile” seems not to be derived directly from Tírechán, but to depend on another source, in which the words _ut uideret fructum sui laboris_ occurred (_Hist. Britt._ 197₁₈, Tírechán, 323₅), and some other expressions common to both. The date of the fifth year of Loigaire (196₆) might have been, but need not have been, taken from Tírechán. (3) The three petitions of Patrick (197) are identical with and correspond verbally to those which are added in the _Liber Armachanus_ to the incomplete text of Tírechán (331); and the four points of comparison with Moses (198) are also found in the same order among these _Additions_ to Tírechán (332). The dates in c. 55 do not correspond to the dates in the _Additions_ to Tírechán. The statement that he was ordained in his twenty-fifth year seems to stand alone. But the period of eighty-five years assigned to his preaching in Ireland has arisen, we may surmise, from a confusion of numerals (lxxii. and lxxxu.). * * * * * It is unnecessary to deal here with the notices of Patrick in the Chronicles of Marianus Scotus (_ob._ A.D. 1083: text in Pertz, M.G.H., V., and Migne, P. L. 107, but these are superseded by MacCarthy’s _Codex Palatino-Vaticanus_, No. 830, 1892 [Todd Lecture Series III.], to which I may refer for a discussion of the dates). Nor need I speak of Jocelin’s biography (twelfth cent.) since it is founded on sources which we possess, and the only value which it may have for Patrician researches is that a minute examination might conceivably show that Jocelin used different recensions of some of our documents. For the purpose of the present biography, such pieces as the Homily on St. Patrick in the Lebar Brecc (printed by Stokes in _Vit. Trip._ vol. ii.), or the prefaces to the Hymns of Sechnall and Fíacc, do not demand particular notice. III 1. _The Irish Annals_
