The DuBourg Belles Heures, attributed to the Master of Jean Charpentier, Tours (?) 1475-1480.
The illuminations in the picture show Saints Adrian and Sebastian.
The Horarium contains 13 large and 14 small illuminations of Annunciation, Visitation, Nativity, Circumcision, Adoration of the Magi, Presentation in the Temple, Massacre of the Innocents, Flight into Egypt, King David in Prayer, dedication page, and images of saints.
This late gothic book of ours is a centre piece in the permanent collection of Wheaton College, a wonderful and ecclectic treasury.
To my class on the history of communication technology, the Wheaton Permanent Collection offers the most valuable opportunity to experience communication artefacts like this beautiful manuscript of the time of Louis le Prudent.
