(Spanish for The Maids of Honour) is a 1656 painting by Diego Velázquez, the leading artist of the Spanish Golden Age, in the Museo del Prado in Madrid. The work's complex and enigmatic composition raises questions about reality and illusion, and creates an uncertain relationship between the viewer and the figures depicted. Because of these complexities, Las Meninas has been one of the most widely analyzed works in Western painting.
