A single line of inquiry has been left to the American student. We have lists of the MSS. in the various libraries of Europe. If it were only possible to examine these with reference to the _Veni Sancte_ the matter could be definitely settled. The Rheinau (Reichenau) library is rich in hymnaries. Haenel’s “No. 53”—whose library number is 91—is, for instance, a _Liber hymnorum_ of the tenth to the twelfth centuries. There are several others—breviaries and collections of hymns—dating to the twelfth century; and one book, “No. 124” (Lib. No. 75), which is marked _Sequentiae propriae_, etc., and which is likely to have the _Veni Sancte_. In the eleventh century at St. Gall they have “No. 381” (St. Gall No. 486) which is a _codex insignis_—a very beautiful MS.—containing the “earliest collection of hymns and poems of writers dwelling at St. Gall.” In this same century appears the Anselm, which is noted as a _codex nobiliter scriptus ab Herimanno, qui se hoc libri decus ex voto perfecisse testatur_ (_pag._ 6), a manuscript elegantly written by Hermann [“Herimann” is his own spelling of his name in the _Chronicon_, by the way], who says on page 6 that he has accomplished this excellent volume in pursuance of a vow. Among these St. Gall MSS. can be found the _Salve regina_, bearing the date 1437. If it were made a point of investigation it might be discovered that in both Reichenau and St. Gall the _Veni, Sancte Spiritus_ is in codices which utterly remove it from the perplexity of its authorship, and positively join it to the name of Hermann. One can sum up the whole discussion in a few sentences. Robert wrote no other valuable hymns; Hermann did write several. Robert was not specially skilled in metrical science; Hermann was the author of a treatise on the subject. Robert was a poet and a musician; Hermann was his superior in both departments. Robert had trouble and sorrow and Christian experience; Hermann must certainly have had as much as he, and more. Robert has had poems attributed to him which have failed of proof, and none of his own verses seem ever to have been misappropriated or missing; Hermann has had more taken from him than given to him. In the matter of authority we are to note: 1. That the historians of St. Gall and of Reichenau claim for Hermann the _Veni Sancte_. 2. That the hymn is found in the earliest codices of both places; and of Einsiedeln, which is in the neighborhood. 3. That Clichtove is in doubt and Daniel is in doubt; that J. A. Fabricius and Du Meril incline toward Egon’s statement; that Trithemius is not entirely unprejudiced; and that Migne, gathering nearly everything (as I have verified from the originals), leaves a strong presumption in Hermann’s favor.
