Les Très Riches Heures du Duc de Berry is a volume of 208 folios (416 pages) measuring 213 by 292 mm (breadth and height, respectively). The work’s calligraphy and illustrations are exceedingly beautiful: more than 3,000 gilded initials and 130 illuminations (65 of which full-page), and an equal number of smaller illuminations within the columns of the text. In the 35 full-page illuminations which we may ascribe with certainty to the Limbourg brothers, we note the artists’ impressive powers of observation, the considerable attention they paid to naturalistic representation, and the elegance and refinement of the end result. We may also note the brothers’ versatility and skill in combining a variety of compositional plans and sophisticated iconographic motifs, while availing themselves of an unusually broad range of pictorial techniques and materials. The palette was, in any case, a rich one – bearing witness to the brothers’ wealth of creative powers in the field of colour.
