The Gospel Illustrated by Duccio by John Joy, S.T.L.

The Gospel Illustrated by Duccio is a unique book designed to celebrate one of the greatest artistic masterpieces of the high medieval period while also bringing to life the Gospel story with over fifty images of scenes from the lives of Jesus Christ and the Blessed Virgin Mary. The book includes the complete extant cycle of images from the Maesta Altarpiece, which Duccio di Buoninsegna completed in 1311 for the Cathedral of Siena. Each large, full-color image is paired with the text, most drawn directly from the Canonical Gospels, which tells the story illustrated by the painting. Not as well known now as they were in Duccio's time, their discovery will be a delight for modern readers, and a welcome alternative to the banal art of many "children's bibles."
