Note 14 — THE CASTLE-HILL.

‘The monograms of the name of our blessed lady are formed of the letters M. A., M. R., and A. M., and these stand respectively for Maria, Maria Regina, and Ave Maria. The letter M. was often used by itself to express the name of the Blessed Virgin, and became a vehicle for the most beautiful ornament and design; the letter itself being entirely composed of emblems, with some passage from the life of our lady in the void spaces.’—Pugin’s Glossary of Ecclesiastical Ornament and Costume, 1844.
