The Calling of Saint Matthew (1599–1600). Contarelli Chapel, San Luigi dei Francesi, Rome. The beam of light, which enters the picture from the direction of a real window, expresses in the blink of an eye the conversion of St Matthew, the hinge on which his destiny will turn, with no flying angels, parting clouds or other artifacts.
National Gallery of Ireland, Dublin. Caravaggio's application of the chiaroscuro technique shows through on the faces and armour notwithstanding the lack of a visible shaft of light. The figure on the extreme right is a self-portrait.
