Arthurian Matters of Britain explores a world inspired by the Celtic, Christian, and Islamic traditions, and arrives at new interpretations of the old stories, including Sir Gawain and the Green Knight and the legends of the Grail. Mahmoud Shelton returns here to his roots in Medieval Studies while deepening his research into the ancient landscape of Glastonbury. More than a study of the past, however, Arthurian Matters of Britain demonstrates how this living world of symbols informs the reign of King Charles III, the "Green Man King."
