tenebroso or tenebrism - Tenebroso is an Italian word, literally meaning dark and gloomy. Both tenebroso and its English equivalent, tenebrism, refer to a style of painting characterized by high contrast between light and shade -- emphasis placed on chiaroscuro to achieve dark, dramatic effects. Frequently the main subjects of tenebrist pictures are illuminated by a single source of light, as if a spotlight shone upon them, leaving other areas in darkness. Such pictures have been called "night pictures" painted in the "dark manner." The most reknowned tenebrists have been "Caravaggio", Michelangelo Merisi (Italian, 1571/73-1610), Georges De La Tour (French, 1593-1652), and Rembrandt van Rijn (Dutch, 1606-1669).
