The original meaning of the term “retablo” referrs to sculptures or paintings that were placed behind altars of Catholic churches. Retablos are important to Mexican folk religion because they are a physical representation of holy images such as the Christ, the Virgin Mother, or one of many other saints. Creating retablos or ex-votos was a way of showing appreciation to the gods for bringing rain or helping crops grow. They evolved from the need most humans have, to interact on a personal level with the divine.
