Step-by-step explanation:
The Limbourg Brothers' October Calendar from Les Tres Riches Heures du Duc de Berry emphasizes rituals of the month and changing aspects of nature primarily by b) depicting agricultural activities and seasonal changes. This illumination does not focus on religious ceremonies or symbols, political events, royal celebrations, or abstract patterns. Instead, it captures the essence of the time by portraying the rural activities and the cyclic nature of the changing seasons that dictated the agricultural life of the period. The artwork reflects the society's connection to the land and the importance of farming in daily life, which is an accurate portrayal of the present times, much like Bruegel's Wedding Feast.
