"The imperial acclamations, a form inherited from Roman antiquity, easily made the transition to a liturgical celebration confirming the sovereign's legitimacy as a ruler chosen by Christ, a protector of the Church. In the Carolingian period these 'Laudes Regiae' were transformed into a dazzling display of litanies celebrating saints and kings alike." Sequentia (Benjamin Bagby, director) and Dialogos (Katarina Livljanić, director) perform "Christus vincit" ('Laudes regiae'). Christus vincit ('Laudes regiae') Text: Paris, BNF, lat. 13149 ca. 796-800. Melody: reconstruction by K. Livljanić based on Paris, lat. 1118, ca. 990.
