Setting aside Innocent III. for cause—although Brander of St. Gall, in his _Index Sequentiarum_, grants this to him—the authorship of the hymn rests between the king and the monk. I say “for cause,” since Innocent was at the summit of temporal power, and his position was a very tempting one to posthumous flattery. He is credited with the _Ave mundi spes Mariae_. He did not write the _Stabat Mater_, nor did he compose the _Veni Sancte_. Let any one examine the _Ave mundi_ and he will renounce all hope that the man who prepared this could ever have written the others, or either of them. Besides, Wrangham is likely to be correct when he assigns this latter sequence to Adam of St. Victor. It is precisely in Adam’s style of metrical composition; it is not found before the fourteenth century, and its tone is modern. It can therefore be said that Innocent deserves no place among the Latin hymn-writers. Now, Robert II. is much in the same condition as Innocent III. His is a shining name to which to affix popular hymns. He has been credited with the _Ave maris stella_—the parent of all hymns to the Virgin. The sequence _Sancti Spiritus adsit_ is not his, on the testimony already adduced; but in the year 1110 the “ancient customs of Cluny,” collected by St. Udalric (Hermann’s ancestor) gives us this “at Pentecost” (D’Achery: _Spicilegium_, I., 641), with the “response,” _Spiritus sanctus_. This would serve to show that such praise to the Holy Spirit was usual. With the _Chorus Novae_ we have already dealt. And the _Rex omnipotens_ belongs to Hermann though it is ascribed to Robert—another instance of inaccuracy, which casts a ray of light upon the present problem. Those sequences of which Robert was the possible author are printed in Migne’s _Patrologia_ (141, 959 _ff._). Only one of them merits a word of notice. It is the _Te lucis auctor personent_. Daniel assigns this to the fourteenth or fifteenth century, but Mone and Koch to the fifth. These last are probably right. It is early found in the Anglo-Saxon Church and is among the old Vatican MSS. and the hymns collected by G. Cassander. It is scarcely possible that it comes down as late as the eleventh century.
