It is to be observed, indeed, that the tendency is entirely absent from Part I. This, however, would hardly justify us in assuming a different authorship or date for the composition of Part I.; inasmuch as the subject matter of this part (Patrick’s childhood, youth, arrival in Ireland, and the Tara legend) did not offer opportunities for urging the Armagh claims. It may also be observed that all the references to events later than A.D. 800 occur in Parts II. and III. The last paragraphs of Part I. (pp. 60-62), which are omitted in the Rawlinson MS., have clearly been inserted here from the end of Part III. (pp. 256-8). The motive of this repetition is, doubtless, supplied by a remark of Dr. M’Carthy: “That upon the recurrence of his festival a sketch of the life and labours of St. Patrick should be delivered in the churches of Ireland would be a procedure in mere conformity with ecclesiastical usage.” The _Tripartite Life_ was practically used as material for sermons, though we may not feel warranted to go so far as to say that it represents sermons reduced to literary form. The particular paragraphs in question were added to Part I. as a “wind-up” for pulpit purposes. There is a similar but shorter wind-up to Part II. Among these added paragraphs (p. 60 = p. 256) occurs a bibliographical notice:— “These are the miracles which the elders of Ireland declared and connected with a thread of narration. Colombcille, son of Fedlimid, first declared Patrick’s miracles and composed them. Then Ultan, son of Conchobar’s descendant; Adamnan, grandson of Tinne; Eleran of the wisdom; Ciarán of Belach Duin; Bishop Ermedach of Clochar; Colman Uamach;[325] presbyter Collait of Druim Roilgech” (trans. Stokes). Of these works we know nothing, though we may suspect that “Ultan” may refer either to the memoir of Tírechán (cp. the lemma in the _Lib. Arm._) or to the book which Ultan lent to Tírechán. Observe that no mention is made of Muirchu’s Life. But Muirchu was certainly a source of the _Tripartite_. If, therefore, this list represents the works which were used in the compilation, the compiler did not use Muirchu’s Life directly, but some later work in which it had been wholly or partly incorporated. This agrees with a conclusion which I had entertained on other grounds, namely, that the compiler used W (the common source of V₂ and V₄) in which the Muirchu narrative had been incorporated with non-Muirchu material. The inference would be that the author of W is to be sought in the list. For instance, Ciarán of Belach Duin, who died A.D. 775,[326] would suit chronologically.
