Musical Epigraphies of Antiphon <i>Salve Regina</i> by Cristóbal de Morales: The Walls of the Sanctuary of Nuestra Señora del Pueyo, Villamayor de Gállego, Zaragoza

In 1990 a publication by Pedro Calahorra reported a unique musical notation of a <i>Salve</i> on the walls of the Sanctuary of Nuestra Señora del Pueyo in Villamayor de Gállego, Zaragoza. The contributions offered in this article have enhanced research in this area through a revised study of this musical epigraphy. The analysis of the palaeography of notation reveals the dating of the work and, therefore, a possible collation with the Spanish polyphonic sources belonging to the white mensural notation, determining that it is the <i>Salve Regina</i> in four by Cristóbal de Morales. This study aims to recognize musical epigraphies as historiographic-musical sources of information capable of intervening in the reconstruction of a musical past, so they must be restored, preserved, catalogued and displayed like any historical document, regardless of their physical support. The <i>Salve Regina</i> written on the walls of the Villamayor de Gállego sanctuary is the witness of a Christian tradition of devotion to the Virgin Mary. Within the Rite of <i>Salve</i> this chant was the most popular in the Iberian Peninsula during the Renaissance.
