sung to the image, there are a number of Masses and it is possible to receive a "visit" by the image of another saint from another neighborhood. During one of the Masses, there is a ceremony to name a new mayordomo, which is usually attended by mayordomos from other neighborhoods. After this mass, food is offered to all in attendance.
