1 December 2009 - 1 April 2010. From still life and portraits to winter landscapes and seascapes, all the characteristic genres of the Dutch school of painting are presented at the Museo Nacional del Prado. Central to the exhibition is Rembrandt's 'Artemis' (also known as 'Judith before Holofernes'). The main activity in what is generally meant by 'Dutch painting' took place in the 17th century in the Northern United Province, which became an independent nation following the Treaty of Utrecht in 1579. Many of the paintings on show have not been displayed since the 1940s.
