 Mary is often pictured with a crown or Circle of Stars.The doctrine of the Immaculate Conception was somewhat controversial in the medieval church, and the liturgical Office for the feast was only established in 1615.In 1649, Francisco Pacheco (father-in-law of Velázquez) published his "Art of Painting" firmly establishing the detailed correct iconography for paintings of the Virgin of the Immaculate Conception, which included the circle of stars (he also advised the inquisition in Seville on artistic matters).
