The painting below is attributed to the workshop of Roger van der Weyden and located at the Royal Museums of Fine Arts Belgium. Its title is King David Receives the Water of Bethlehem. Measuring 50cm x 32.7cm, the painting is dated between 1451 and 1475. It appears to be a section of a larger work but I don’t have access to any information to confirm this.
Three painters are featured in the foreground: Roger Campin, Rogier van der Weyden and Jan van Eyck.
