<P> The Mérode Altarpiece (or Annunciation Triptych) is an oil on oak panel triptych, now in The Cloisters, in New York City . It is unsigned and undated, but attributed to the workshop of the Early Netherlandish painter Robert Campin . The three panels represent, from left to right, the donors kneeling in prayer in a garden, the moment of the Annunciation to Mary, which is set in a contemporary, domestic setting, and Saint Joseph, a carpenter with the tools of his trade . The many elements of religious symbolism include the lily and fountain (symbolising the purity of Mary), and the Holy Spirit represented by the rays of light coming falling from the left hand window . </P> <P> Art historian's interest in the Mérode Altarpiece focuses mainly on the central panel, which was completed after 1422, likely between 1425 and 1428, by a member of Campin's workshop . The outer panels are later additions by a workshop member, probably on request by the donor who sought to elevate the central panel to a triptych and place himself in the pictorial space . The wings contain views of the city of Liège, in today's Belgium . A version of the center panel in Brussels is earlier, and maybe Campin's original panel . </P>
