The antiquity of this source is proved by the following facts: (1) Cothraige, the Goidelic form of Patricius, appears in an older form with initial _q_ (_Quadriga_, _Quotirche_), which points to a document older than the seventh century (since Tírechán has initial _c_); (2) this Goidelic name, not Patricius, appears in the part of W which related Patrick’s dealings with Miliucc; (3) the name Succet takes the place of “Quadriga” where his sister Lupita recognises him, as it is the name by which she would have known him: such traits of verisimilitude are not likely to have been introduced by late compilers. It is probable that this source was in Irish. This would account for the Irish bits in W preserved in V₂. And the Irish source, from which W supplemented Muirchu, probably resembled (being based on the same material) the Irish source which Muirchu used for his Life. In this connexion it is to be observed that W and Muirchu give variant renderings of the prophecy of the Druids, pointing to variant versions of the Irish original. As for the latter part of V₄, where V₂ fails us, it seems probable that W was also a source, though there may have been other sources (cp. Bury, _Tradition_, etc., p. 195).[320] 7. _Vita Tripartita_ A Life of Patrick written in Irish (but largely interspersed with Latin passages and clauses) is extant. A Latin translation of it was published by Colgan, who named it the _Vita Tripartita_ because it is divided into three parts. This translation represents a different text from that preserved in the two existing MSS. from which Dr. Stokes published the _editio princeps_ of the Irish text (Rolls Series, 1887). This edition can hardly claim to be critical, as no attempt whatever is made to establish the mutual relations of the MSS.[321] It is clear, even on a superficial examination, that the two extant MSS. imply an archetype representing a tradition different from the text which Colgan followed.
