A great source for people studying medieval music is the Pórtico da Gloria on the medieval façade of the Cathedral of Santiago in Santiago de Compostela, Spain. The sculptures were completed between 1168 and 1211 by Master Mateo. In the central archivolt the elders of the Apocalypse play musical instruments including an organistrum, guitar, cittern, harp, aulos and eight violas and for percussions: bells, tambourines and castanets. In addition to being a great source of medieval musical instruments, the sculptures aptly portay the bliss of music.
