Act for the Immaculate Conception of Mary

Act for the Immaculate Conception of Mary (Catalan: Acte per a la Immaculada Conceptio de Maria) is the name of a dramatic play, in the Catalan language, likely performed in Bethlehem College in Barcelona on May 13, 1662, to celebrate a declaration of Pope Alexander VII in support of the idea of Immaculate Conception. The work argues for the absence of original sin in the one who was to become the Mother of God.
