A 15th-century Dutch duchess whose name is immortalized by a breathtakingly beautiful and eccentric illuminated prayer book, a masterpiece of medieval art.
Catherine of Cleves lived a life of noble duty, but her lasting fame comes from an object of profound personal devotion. As Duchess of Guelders through marriage to Arnold, she navigated the complex politics of the Burgundian Netherlands and even acted as regent. History, however, remembers her primarily as the patron behind the 'Hours of Catherine of Cleves,' created around 1440. This book of hours is not merely a prayer text; it is a window into a whimsical and deeply spiritual imagination. Its pages are filled with startlingly inventive marginalia—monkeys, dragons, and everyday objects intertwined with sacred scenes. The manuscript stands as one of the most original and masterful examples of Dutch illumination, ensuring that the duchess's name is synonymous with a unique artistic vision that transcends her political role.

The world at every milestone
Her book of hours was split into two volumes in the 19th century, which were reunited at The Morgan Library & Museum in New York in 2009.
The manuscript's illustrations include surprisingly humorous and secular details, like a nun feeding a monkey and a man with a toothache.
She was a great-aunt of Anne of Cleves, the fourth wife of England's King Henry VIII.
“My prayer book is my private world, a garden of color and faith.”
