||Snow 2007: "This study, by revealing the true complexity of book-making strategies, types of in-house (scriptorium) intervention actually practiced, and the problems inherent in contemporary concepts of "authorship", cautions scholars about assigning to Alfonso, to Airas Nunes, or to others, full authorship of any composition of the Cantigas de Santa Maria. Well-reasoned, important contribution at a critical moment in Cantigas studies."
