Ave regina coelorum. [Blessed Virgin Mary.] One of the four Antiphons to the B. V. M. (see "Alma Redemptoris mater"). Among the manuscripts in the British Museum it is found in the St. Alban's Book of the 12th century (mss. Reg. 2 A. x. f. 62), and a Sarum Breviary of the 14th century (mss. Reg. 2 A. xiv. f. 235 b). It is also in the York Breviary, 1493 (1883 reprint, ii. 493); in the Roman Breviary, Modena, 1480, f. 512, &c. The text in Daniel, ii. 319, is from a Munich manuscript probably of the 13th century, and other sources. [Rev. James Mearns, M.A.]
