Bats invaded Carlota Valdez's house and flew over her bed at nights and they filled her with nightmares and their dreams. She feared they could be vampires and would suck her and her cats' blood and they would be converted into the living dead for all Eternity. Very worried, Carlota prayed to Saint Quiteria for protection. The saint worked a miracle for her, the bats left to live somewhere else, and Carlota gives thanks with this altarpiece.
An ex-voto is created when an individual's prayers for a miracle are answered. After praying to a saint for a miraculous healing, an individual would commission a local artist to create a small painting that would be hung in the local church as a public testimony of that individual's faith and gratitude for a miracle.
