The Cantigas de Santa Maria (Galician: [kanˈtiɣɐz ðɪ ˈsantɐ maˈɾi.ɐ], Portuguese: [kɐ̃ˈtiɣɐʒ ðɨ ˈsɐ̃tɐ mɐˈɾi.ɐ]; “Canticles of Holy Mary”) are 420 poems with musical notation, written in the medieval Galician-Portuguese language during the reign of Alfonso X of Castile El Sabio (1221–1284). Traditionally, they are all attributed to Alfonso, though scholars have since established that the musicians and poets of his court were responsible for most of them, with Alfonso being credited with a few as well.[1]
