In the classical world, the “Apotheosis” refers to granting the dignity of gods to heroes. In Christianity, the term represents the glorification of a person by the community. In this work, divine manifestation is expressed with very subtle characteristics: the presence of angels, keys and the exact posture of Saint Peter, who is a common man. Naturalism is a characteristic trait of XVII century Spanish Baroque art. It is proximity of that which is human and the eloquence of images from daily life. Artists used people from their environment as models, exactly as the painter Diego Velázquez did in Seville.
