At Toledo, king Alfonso VI of Castile did not recognize the Mozarabs as a separate legal community, and thus accentuated a steady decline which led to the complete absorption of the Mozarabs by the general community by the end of the 15th century. As a result, the Mozarabic culture had been practically lost. Cardinal Cisneros, aware of the Mozarabic liturgy historical value and liturgical richness, undertook the task of guaranteeing its continuation, and to this end gathered all the codices and texts to be found in the city. After they had been carefully studied by specialists, they were classified and in 1502 the Missal and Breviary were printed. They revitalised the faith and a Chapel was instituted at the Cathedral, with its own priests which still exists today.
