Nicolaes Pieterszoon Berchem (October 1, 1620 – February 18, 1683) was a respected and prolific Dutch Golden Age painter, particularly noted for his pastoral landscapes, allegories and genre pieces. His works were often populated with mythological figures. In the late 1650s he worked for Nicolas Visscher I, designing the latter's atlas and engraving (at least) the world map of that atlas. His work exemplified the Dutch Italianate landscape style of painting, employing classical ruins and pastoral imagery based on visits, or imagined visits to the Italian countryside. He was born in Haarlem, and was educated both by his father and an array of painters including van Goyen, de Grebber, Weenix, Wils and Moeyaert. He appears to have been an avid collector of prints as well: After marrying the daughter of his teacher Jan Wils, she kept him on a small allowance - but in order to support his collecting habit, he borrowed money from students and colleagues, later paying them back from the proceeds of paintings executed with his wife's knowledge. He was apparently a popular teacher with many painters having come up under his tutelage. We are not aware of how popular he may have been with his wife.
