Beata nobis gaudia Anni reduxit orbita. [Whitsuntide.] This hymn is sometimes ascribed to St. Hilary of Poitiers; but as in the case of others, upon insufficient evidence. The full text, in 6 stanzas of 4 lines, is given in Daniel, i., No. 7, together with the Roman Breviary version, and a few references, and notes. Mone, No. 183, gives the text from manuscripts of the 13th and 14th centuries, supplies readings therefrom and closes with a note. Daniel, iv. pp. 160-161, quotes Mone almost verbatim, and adds readings from a Rheinau manuscript of the 11th century. The text is also found in two manuscripts of the 11th century, in the British Museum (Jul. A. vi. f. 53 b., Vesp. D. xii. f. 78); the Latin Hymns of the Anglo-Saxon Church, 1851, p. 93, where it is printed from an 11th century manuscript at Durham; in the Hymnarium Sarisburiense, Lond. 1851, pp. 113,114; in Card. Newman's Hymni Ecclesiae, 1838 and 1865; in Simrock, 1868; and other collections.
