Nato canunt omnia. [Christmas.] This sequence is found in the Bodleian manuscript, No. 775, written about the year 1000 (f. 139 b); in an 11th century Winchester Sequentiary, now at Corpus Christi, Cambridge (ms. No. 473); an 11th century manuscript at Munich (Lat. 14083, f. 7), &c. In the Sarum, Hereford and York Missals it is placed in the Midnight Mass ("Missa in Gallicantu") of Christmas Day. The printed text is also found in Daniel ii. p. 56, and Kehrein, No. 9. Clichtovaeus represents it as describing the joy of Christmas, announced by the angel to the shepherds, and sung by the angelic choir; and as inviting the whole human race to rejoice in God made Man. [Rev. James Mearns, M.A.]
