The Immaculate Conception
Museum of the Church of San Paio (St. Pelagius), Santiago de Compostela, Spain
This is the iconography that developed in the 17th century from Revelation 12:1, "And a great sign appeared in heaven: a woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars." The text goes on to say that the woman was about to give birth and that a red dragon stood by planning to devour the child. Like most other Immaculate Conceptions this statue includes the dragon but not any indication of pregnancy.
Besides the crown of stars, a few other examples of this iconographic type will also give the figure an actual crown. The addition of an angel or angel face to the moon is also seen occasionally.
