The majority of researchers agree in putting in the 14th century the birth of the iconography were the devotion for Saint Anne as mother of the Immaculate, was captured. The success of the devotion is clear when we consider that it ended up being one of the most popular themes of Spanish medieval sculpture. Based on apocryphal texts, the representation, far from revealing a theological reality, was the result of a popular imagination that wanted new arguments to fell sacred figures closer. This is why, after the theme purge of the Council of Trent, its presence in art declined considerably. It is difficult to establish a specific production area for an artisanal sculpture that is iconographically repeatedin different Spanish regions from which there are still missing complete records. However, in this case we can propose, at least as a hypothesis, an Aragon origin by its similarities in carving as well as in the type of polychromy of that region. Anyhow, it is a piece of great interest for the collection of medieval sculpture of the Museum because to its age and quality, we have to add an important preservation of its original polychromy.
