Retablos are sophisticated folk art in the form of portable boxes filled with brightly colored figurines arranged into intricate narrative scenes. From the 16th to the 19th centuries, Retablos were carried through the mountains by Spanish priests as portable religious shrines for Catholic saints. Later, they were adapted by indigenous people to include their own deities and mythologies.
