"The Beheading of St. John the Baptist"

The painting typifies Caravaggio’s signature chiaroscuro technique which is described as Caravaggio going  so far in this style that he never showed any of his figures in open daylight, but instead found a way to place them in the darkness of a closed room, placing a lamp high so that the light would fall straight down, revealing the principal part of the body and leaving the rest in shadow.
