In the 1470s, one of the most innovative artists working in Bruges illuminated a Book of Hours for Jean Carpentin, lord of Gravile and prominent citizen of Normandy. Known as the Master of the Dresden Prayer Book after one of his other masterpieces, this artist and members of his workshop enriched the pages of Carpentin's manuscript with miniatures, historiated initials and boldly colored borders in which human figures, monsters and monkeys are framed by twisting branches of acanthus.
