The Ascension; Book of Hours, about 1410. Additional Info:The twelve apostles and the Virgin Mary gaze upward as Christ ascends into heaven. Only Christs feet are visible as he disappears into the dark blue cloud at the top of the image. His footprints can still be seen imprinted on the rock below. The entire scene is set against a checkerboard of red, blue, and gold squares called a diapered ground, which was a common decorative motif in International style painting. This image precedes the prayers for the feast of the Ascension in a devotional book that was probably used by a layperson to follow along with the mass.
