On an altar in a green meadow stands the Lamb, and its blood runs into a chalice. Angels kneel around it. From all four sides groups of people approach across the grass: prophets and apostles, popes and hermits, and women with palms in their hands.
This is the lower central panel of the Ghent Altarpiece, completed in 1432. An inscription on the frame says that Hubert van Eyck began the work and his brother Jan finished it. The meadow is painted flower by flower; botanists have identified dozens of species.
