The surviving Lives naturally divide themselves into two great classes-- the Latin Lives and the Irish,--written in Latin and Irish respectively. We have a Latin Life only of some saints, and Irish Life only of others, and of others again we have a Latin Life and an Irish. It may be necessary to add the Acts which have been translated into Latin by Colgan or the Bollandists do not of course rank as Latin Lives. Whether the Latin Lives proper are free translations of the Irish Lives or the Irish Lives translations of Latin originals remains still, to a large extent, an open question. Plummer ("Vitae SSm. Hib.," Introd.) seems to favour the Latin Lives as the originals. His reasoning here however leaves one rather unconvinced. This is not the place to go into the matter at length, but a new bit of evidence which makes against the theory of Latin originals may be quoted; it is furnished by the well known collection of Latin Lives known as the Codex Salmanticensis, to which are appended brief marginal notes in mixed middle Irish and Latin. One such note to the Life of St. Cuangus of Lismore (recte Liathmore) requests a prayer for him who has translated the Life out of the Irish into Latin. If one of the Lives, and this a typical or characteristic Life, be a translation, we may perhaps assume that the others, or most of them, are translations also. In any case we may assume as certain that there were original Irish materials or data from which the formal Lives (Irish or Latin) were compiled.
