I don't think you'll be able to express this in one word. S. Wikipedia on Michael Pacher, whose altar in the church of St. Wolfgang is one of the most splendid examples of this kind of sacred art.
"Fortunately, his most famous work, the Altarpiece of St. Wolfgang remains secure at the Church of St. Wolfgang on the Abersee in Austria. The altarpiece is a polyptych, or Wandelaltar, where a painting is often divided into four or more segments or panels. There are two pairs of movable wings, and three clearly different viewpoints for use on different circumstances; one for every day views, Sunday views, and then views for special holy days. Commissioned for Abbot Benedict Eck of Mondsee in 1471 and completed in 1481, the giant polyptych has two sets of wings that can be closed across the inner corpus with the sculptured Coronation presenting a majestic array of huge Gothic figures dominated by the beautifully kneeling Madonna. The carved and painted gold centerpiece is visible when the inner panels are open, and represent the Coronation of the Virgin. The outer two pairs of painted wings represent four scenes from of Saint Wolfgang. Wolfgang was appointed as bishop Benedictine of Ratisbon, where he established himself radiantly for his revolutionary passions and also for his skills as statesman. The entire altarpiece is overshadowed by an elaborate wooden structure that is placed on top, enclosing the Crucifixion. In the centerpiece Christ is sitting on a throne sincerely blessing Mary, whom he has crowned as the Queen of Heaven. In keeping with the traditions of German Gothic art, angels are fluttering around while John the Evangelist looks on. The inner faces of the second panels, on both sides of the carved body, are painted with scenes from the life of the Virgin."
