So many sources from Medieval Spain feature songs that lead people to understand how to be a Christian; indeed, the world’s first how-to guide was a travel guide along the Camino de Santiago pilgrimage route to Galicia. It was not at all straightforward to be a Christian in Spain because many other faith traditions co-existed. Thus, those in leadership of churches, cathedrals, and even kingdoms found it necessary to create art and music that also encouraged the faithful to walk a Christian path. From the Codex Calixtinus in Galicia to songs out of the Huelgas Convent, cantigas by King Alfonso X to the Llibre Vermell in Montserrat, all of these sources include songs and dances that praise, inspire, and lead the Christian faithful to become more pious, songful, and devoted to God through the Virgin Mary and her Son.
