Final answer:
Jacques-Louis David's painting Death of Marat uses tenebrism to achieve dramatic contrasts and highlight the tragic death of Jean Marat, enhancing the painting's emotional impact.
Step-by-step explanation:
Jacques-Louis David's painting Death of Marat incorporates tenebrism, the use of dramatic dark and light to heighten a painting's impact. Tenebrism is a style of painting that uses very pronounced and dramatic light contrasts (chiaroscuro), with darkness being a dominant feature of the image. This technique was popularized by Caravaggio and is characterized by the stark contrast between light and dark areas within a painting, creating a dramatic, intense effect.
David's use of tenebrism in Death of Marat contributes to the portrayal of Jean Marat as a martyr, capturing the solemn and tragic moment just after Marat's murder. The dramatic lighting emphasizes the stillness of Marat's body and the gravity of the event, reflecting the tumultuous period of the French Revolution.
