Petrus Christus (c. 1415 Baerle, near Antwerp 1472/73 Bruges) is considered one of the most important successors of Jan Van Eyck, and was a leading representative of the Bruges School. Upon van Eyck's death, Christus took over his workshop in 1441 after having been his assistant, and completed several works that van Eyck had left unfinished. He was also greatly influenced in the 1440s by the art of Roert Campin and Rogier van der Weyden. Christus further developed the use of perspective by empirically discovering the law of linear perspective and applying it to his painting. He was the first artist to paint portraits of sitters in front of an interior. Recent research, in particular, tends to evaluate him increasingly as an independent artist rather than as a mere imitator of the great masters. His landscapes are also of significance: in these, he applied the basic rules of perspective in a manner that broke new ground for his successors. Among his major works are The Carthusian Monk, 1446, The Metropolitan Museeum of Art, New York; St. Eligius as a Goldsmith Gives a Ring to the Bridal Couple, c. 1449, The Metropolitan Museum of Art, New York; and The Nativity, 1452, Gemaldegalerie, SMPK, Berlin.
