Questões em torno da unanimidade litúrgica no mosteiro de Alcobaça - séculos XIII a XV

This article focuses on the issue of the Cistercian liturgical standardisation in the context of Alcobaça abbey between the 13^th and the 15^th centuries. The problematics of this issue will be carried out through the analysis of some of its manuscripts, including liturgical manuscripts such as breviaries and other codices supporting liturgy. These manuscripts constitute an important source of information on the daily practice of the liturgy in the abbey's context, on the implementation of the guidelines from the Cistercian General Chapters and on their higher or lower permeability to other devotions.
