What medium did the Limbourg Brothers use for their work "October" in Les tres riches heures du Duc de Berry?

The Limbourg Brothers created "October" as part of the illuminated manuscript known as "Les très riches heures du Duc de Berry." An illuminated manuscript is a hand-crafted book that features illustrations, often filled with gold and vibrant colors, enhancing the text. This specific work exemplifies the intricate and detailed style typical of illuminated manuscripts produced in the early 15th century, showcasing not just the artistry involved but also the labor-intensive process of book-making during that era.

The use of this medium allows for rich detail and personalization, which are characteristics of the Limbourg Brothers' works. Their ability to combine text and elaborate imagery created a multifaceted resource that provided both religious and secular insights into the life and seasons of the time, as seen in the depiction of the harvest and agricultural activities in October. The careful detailing and ornate qualities of the manuscript elevate it beyond simple illustration, making it a significant example of Gothic art and culture.
