(2) If the story of the compilation of the Senchus in the reign of Loigaire had been a deliberate invention, say of the ninth century, it could hardly have assumed its actual shape. The persons alleged to have taken part in the compilation would naturally be those who play a prominent or well-marked part in the Patrician story. Now, leaving out Patrick and Loigaire, of the other seven only three, Daire, Benignus, and Dubthach, are conspicuous in the lives and legends of Patrick. Of the other four, Ros appears indeed, but not so conspicuously as his brother Dichu, while Corc, Cairnech, and Fergus are not mentioned at all. The case of Corc, king of Munster, is particularly to be noted, because Oengus (Corc’s second successor) comes into the Patrician story, and would naturally have been selected as Patrick’s colleague if the record were a pure invention. The record, I therefore conclude, has a genuine and ancient basis. It would be rash to be confident that the number nine, and the arrangement in three classes, may not be an improvement upon the original record; in other words, some names (_e.g._ Benignus and Daire) may conceivably be additions. The number nine was considered a number of virtue by the Gaels; and it is conceivable that a savant of a later age might have added to the tradition in order to make up that number. But the argument is double-edged. For it is equally likely that, for just the same reason, the number of the real commission should have been fixed at nine. The story that the occasion of the composition of the Senchus was the slaying of Odhran, Patrick’s charioteer, in order to test Patrick’s doctrine of forgiveness, is told in the Introduction to the _Senchus_ (pp. 4 _sqq._) and in the _Lehor na hUidre_ (text and translation, in Stokes, _Tripartite_, 562 _sqq._). A different story of the death of Odhran at the hands of Foilge is told in _Vita Quarta_, c. 77, and _Vita Tertia_, c. 59 (where the charioteer’s name is not mentioned): according to this version the missile was aimed at Patrick. This version, but without reference to Foilge, is likewise noticed in the Introduction to the Senchus (p. 6). The simplest explanation maybe that a driver of Patrick was slain by an enemy, and that the incident was used by Patrick for raising the question of criminal justice; mythopoeic instinct then attributed the murder to a deliberate intention of raising the question.
