Petrus Christus (c. 1410/1420 – 1475/1476) 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 1446 Portrait of a Carthusian and c. 1470 Berlin Portrait of a Young Girl, both are highly innovative in presentation of the figure against detailed, rather than flat, backgrounds.
Christus was an anonymous figure for centuries, his importance not established until the work of modern art historians. Giorgio Vasari barely mentions him in his biographies of painters, written in the Renaissance, and near contemporary records merely list him amongst many others. In the early to mid-nineteenth century, Gustav Waagen (who identified him in Francophile language as "Pierre Christophsen") and Johann David Passavant were important in establishing Christus's biographical details and in attributing works to him.
Christus was born in Baarle, near Antwerp and Breda. Long considered a student of and successor to Jan van Eyck, his paintings have sometimes been confused with those of van Eyck. At the death of van Eyck in 1441, it is thought that Christus took over his master's workshop. Christus purchased his Bruges citizenship in 1444, exactly three years after van Eyck's death, taking advantage of a decree set down by Philip the Good allowing in men indebted to him after the Bruges Revolt of 1436–38. Had he been an active pupil in van Eyck's Bruges workshop in 1441, he would have received his citizenship automatically after the customary period of one year and one day. Christus may have been van Eyck's successor in the Bruges school, but perhaps not his pupil. Recent research reveals that Christus, long seen only in his predecessor's light, was an independent painter whose work shows just as much influence from, among others, Dirk Bouts, Robert Campin and Rogier van der Weyden.
