When you take the dramatic contrast of light and shadow known as chiaroscuro to a wild, violent extreme—that’s tenebrism. From the Italian tenebroso, meaning ‘dark, mysterious’ Tenebrism became a fixation for artists during the Baroque period. The distinctive ‘spolight’ look appears in work by El Greco, Tintoretto and Dürer, but it was Caravaggio that made it canon.
