Rogier van der Weyden

Very few details of van der Weyden's life are known. The few facts we know come from fragmentary civic records. Yet the attribution of paintings now associated to him is widely accepted, partly on the basis of circumstantial evidence, but primarily on the stylistic evidence of a number of paintings by an innovative master.
Van der Weyden worked from life models, and details were closely observed. Yet he often idealised certain elements of his models' facial features, who were typically statuesque, especially in his triptychs. All of his forms are rendered with rich, warm colourisation and a sympathetic expression, while he is known for his expressive pathos and naturalism. His portraits tend to be half length and half profile, and he is as sympathetic here as in his religious triptychs. Van der Weyden used an unusually broad range of colours and varied tones; in his finest work the same tone is not repeated in any other area of the canvas, so even the whites are varied.
