William A. Christian, Jr., Person and God in a Spanish Valley, Princeton UP, 1972

GRAPH OF OBESO DEVOTION TO REGIONAL SHRINES

The shrines favored by the valley on a more regional level can be followed by studying the death registers of the parishes. Vital statistics began to be kept by the parish priests beginning about 1600 in the aftermath of the Council of Trent. The priests were given directives to pay special attention to the listing of masses to be said for the soul of the deceased according to his or her will.
