King Edgar: Reigned, 1 October 959 - 8 July 975 (from All Souls College Chapel).
King Edgar, c.943-75. A detail from a stained glass window in All Souls College Chapel, Oxford University. This image was originally obtained from Warden and Fellows of All Souls, Oxford University, according to whom, "The large stained glass window [containing this image] in the west wall is known as the Royal Window. Dating from the mid-15th-century but much restored, it was originally located in the Old Library of All Souls." The kings depicted in the window originally included Constantine, Arthur, Ethelbert, Oswald, Alfred, Edmund, Athelstan, Edgar, Edward the Martyr, Edward the Confessor, and Henrys IV-V-VI. Shakespeare could well have seen this image on his frequent visits to Oxford while commuting to London; he stages or alludes to nine of these thirteen names (three in Lear).
