George R. R. Martin's A Song of Ice and Fire has sparked a renewed interest in things medieval. The pseudo-historical world of Westeros delights casual fans while offering a rich new perspective for medievalists and scholars. This study explores how Martin crafts a chivalric code that intersects with and illuminates well known medieval texts, including both romance and heroic epics. Through characters such as Brienne of Tarth, Sandor Clegane and Jaime Lannister, Martin variously challenges, upholds and deconstructs chivalry as depicted in the literature of the Middle Ages.
