Pieter Aertsen
(1508 - 1575) 

Pieter Aertsen called Lange Piet ("Tall Pete") because of his height, was a Dutch painter in the style of Northern Mannerism. He is credited with the invention of the monumental genre scene, which combines still life and genre painting and often also includes a biblical scene in the background. He was active in his native city Amsterdam but also worked for a long period in Antwerp, then the centre of artistic life in the Netherlands.

 Francisco Goya
(1746 - 1828) 
 

Francisco José de Goya y Lucientes was a Spanish romantic painter and printmaker. He is considered the most important Spanish artist of the late 18th and early 19th centuries. His paintings, drawings, and engravings reflected contemporary historical upheavals and influenced important 19th- and 20th-century painters. Goya is often referred to as the last of the Old Masters and the first of the moderns. He is widely regarded as one of the most influential figures in the history of Western art.

 Petrus Christus 
(1410/1420 - 1475/1476) 

Petrus Christus was an Early Netherlandish painter active in Bruges from 1444, where, along with Hans Memling, he became the leading painter after the death of Jan van Eyck. He was influenced by van Eyck and Rogier van der Weyden and is noted for his innovations with linear perspective and a meticulous technique which seems derived from miniatures and manuscript illumination. Today, some 30 works are confidently attributed to him. The best known include the Portrait of a Carthusian (1446) and Portrait of a Young Girl (c. 1470); both are highly innovative in the presentation of the figure against detailed, rather than flat, backgrounds.
