The Prince is brought to Burgundy to meet his aunt, Margaret of Burgundy. Margaret's wealth is influential for Richard and she believes he is the rightful heir, so she wants to support him in whatever ways she can.
"The riches and magnificence of the now extiguished house of Burgundy, almost equalled that of Paris; their cavaliers were as noble and gallant; their tournaments and feasts as gay and pompous. The Prince felt his situation much changed for the better. His aunt's warm affection was more worth than Charles's politic and courteous protection" (156).
Description: The image is a famous painting of Mary of Burgundy. She sits praying and reading from the Book of Hours. In the frame are the church leaders, the Mother Mary and Child, and potentially her husband.
