The Mystical Nativity, ca 1500 by the Italian Renaissance Sandro Botticelli. It has a very unusual iconography for a Nativity. At the top of the painting twelve angels dressed in the colours of faith, hope and charity dance in a circle. In Renaissance times Last Judgment paintings showed viewers the reckoning of the damned and the saved at the time of Christ's Second Coming. In echoing this, the Mystical Nativity is asking us to think not only of Christ's birth but of his return.."
The Incredulity of Saint Thomas, by Caravaggio Chiaroscuro (Italian: “light-dark”) in art is characterized by strong contrasts between light and dark, usually bold contrasts affecting a whole composition. It is also a technical term used by artists and art historians for using contrasts of light to achieve a sense of volume in modeling three-dimensional objects such as the human body.
