The Cantigas de Santa Maria is a vast collection of over 400 pieces, with texts in the Galician language, ascribed to King Alfonso the Wise (c. 1284). While most of the cantigas narrate miracles of the Virgin Mary, the corpus is carefully structured, so that every tenth piece is a song in her praise. This new edition has been prepared with both scholars and performers in mind. The texts have been newly prepared in a regularized spelling, with a parallel English version for those who seek a word-by-word understanding of the original. An introductory chapter, and notes on the individual texts, provide a context for a fuller understanding.
