1. It is clear that the expedition to Tirawley with the sons of Amolngaid was the principal motive of one visit, and that Patrick must have proceeded direct from Tara to Tirawley. Tírechán’s naive reconstruction implies that having left Tara for this purpose he engaged in a round of missionary activity, not only in Connaught, but in Meath—performing labours which would have occupied years—before he finally reached Tirawley. I have pointed out at length the absurdities involved in the story, _op. cit._ 166-7. 2. The description of the visit to Elphin implies earlier work in the same district: (_a_) perhaps the previous foundation of Senella Cella; (_b_) the presence of Assicus and Betheus, who had been settled there (_loc. cit._ 163-4). As to Senella Cella, however, Dr. Gwynn has made a very plausible suggestion, that Tírechán confused it with Senchua = Shancough, in Sligo. The information which he gives about Senella Cella—its location in the land of the Hy Ailella, its association with Mathona, and connexion with Tawnagh—suits Senchua much better. And this comparison would account for the introduction of the statement _et exiit per montem filiorum Ailello_, etc., in 314₁₈, as well as in 328₁. If this view is right, it is another illustration of Tírechán’s use of written sources. The difficulty is that we should expect Tírechán to have been sufficiently acquainted with the geography of Connaught as to know whether _Senella Cella_ was in the land of the Hy Ailella or not. Can _Senella Cella Dumiche_ be distinct from both Shankill at Elphin and Shancough? 3. An earlier visit to Tirerrill is implied by (_a_) Patrick’s knowledge of the stone altar (Tír. 313₅); and (_b_) the fact that Tamnach had already been founded (314₁₅). Here indeed we can extricate a piece of Tírechán’s written material, relating to Patrick’s work in Tirerrill, and showing that he entered that territory from Leitrim, crossing the Bralieve hills, 314₁₈:— Et exiit per montem filiorum Ailello et plantavit aeclessiam liberam hi Tamnuch, and 328, _et exiit ... cell Senchuae_. See Bury, _loc. cit._ 164-6. 4. In the passage in the _Liber Armachanus_, f. 9, rᵒ (301), which Dr. Gwynn has shown (see above, p. 250) to belong to the work of Tírechán, the baptism of Hercaith and the dedication of his son Feradach = Sachellus to the church are noticed; and it is recorded that Patrick ordained Sachellus at Rome. But immediately afterwards at Selce (319) Sachellus is already a bishop (of Baslic, _Trip._ 108). Thus two visits, separated by an interval of years, are here implied. If the statement is correct that Patrick took Sachellus with him to Rome, then our conjectural chronology for his visit to Rome (see Appendix C, 15) would give a lower limit for one of his journeys to Connaught. 5. An earlier visit to north Sligo is implied—but without inconsistency—in the account of the visit to that region (327), as well as in the presence of _bishop_ Brón at Selce (and cp. 313₈).
