Swans possess a striking beauty, and they are imbued with a sense of regal mystery that makes them some of the most fascinating of wild creatures. Introducing the Medieval Swan traces those characteristics to their roots in the medieval era. Opening with a study of the natural history of the swan as understood in the period, the book then moves to literary motifs that feature swans transforming into humans, particularly the legend of the Knight of the Swan. The third chapter examines the place of the swan as an icon of the Lancasters, and the book then explores the swan's place as a delicacy at extravagant feasts. Finally, we learn how the characteristics the medieval era associated with swans developed over the centuries to the present.
