Completed by 1408 or 1409, probably in Paris, "The Belles Heures," a private devotional book, was the first of several sumptuous manuscripts commissioned by the duke of Berry from the Limbourg brothers, Pol, Jean, and Herman. It is perhaps the only virtually complete and stylistically consistent prayer book to survive from the duke's extraordinary library. The richly illustrated text is amplified by unusual cycles reflecting the duke's personal interests. Using a luminous palette, the artists blended an intimate Northern vision of nature with Italianate modes of figural articulation. The keen interest in the natural world and the naturalistic means of representing it, so striking in ninety-four full-page and fifty-four column illuminations, foreshadow the work of Jan van Eyck and the ensuing generations of outstanding fifteenth-century painters in the South Netherlands.For more information about the Belles Heures, including descriptions of all the illuminations with their folio numbers, please see http://blog.metmuseum.org/artofillumination/.
