January page from Très Riches Heures du Duc de Berry (The Book of Hours)
Translated to “The Very Rich Hours of the Duke of Berry”, the book is an illuminated manuscript created between 1412 and 1416. Being a “book of hours” means that it is made up of Christian prayers that would be said at canonical hours. The book was created by the Limbourg brothers: Paul, Jean, and Herman.
The page for January depicts a New Year's Day feast with the Duke of Berry sitting at the table.
