"The Story of the Grail and the Passing of Arthur" by Howard Pyle is a novel published in 1910. This final installment of Pyle's Arthurian series weaves together three legendary tales: the trials of Sir Geraint and his faithful wife Enid as jealousy and misunderstanding threaten their marriage, Sir Galahad's sacred quest to achieve the Holy Grail, and the tragic death of King Arthur himself. Together, these stories bring Pyle's reimagining of Camelot's greatest heroes to a powerful close. (This is an automatically generated summary.)
