Glastonbury in England is a mysterious and mystical blend of Astrology, Solar Worship, Christianity and the legacy of King Arthur on his Isle of Avalon. The Glastonbury zodiac, like Stonehenge, is a temple of the Sun and has existed for more than 4,000 years. Christianity arrived here with Joseph of Arimathea, the uncle of Jesus, who first brought a young Jesus with him on a visit, and then later returned (after Jesus’ crucifixion) in 63 AD, bringing with him the Chalice, or Graal, of the Last Supper.
King Arthur himself was the offspring of one of the Solar Watchers who mated with a married lady known as Ygerne of Cornwall. Ygerne then, under the guidance of the personality known as Merlin, arranged to be married to Uther Pendragon. The ‘hybrid’ Arthur was born c.473 AD and Uther & Ygernee handed Arthur and his sister Morgana (also a Solar hybrid) over to Merlin to be raised as his children. Although never known as a Solar ‘deity’ (they ceased visiting Earth centuries before that), some writers have called Arthur a ‘Solar hero.’
Sir Gawain was the son of Arthur's sister Morgana and was well known to be the most trustworthy friend of Sir Lancelot. It was said that his strength waxed and waned with the Sun; in the most common form of this motif, his might tripled by noon, but faded as the Sun set. The Solar connection to the story of King Arthur is inescapable, although the secrets he taught his Knights of the Round Table are lost to time. In 1935, Katherine Maltwood identified the Vesica-Pisces symbol at Glastonbury Abbey along with the zodiacal form of Pisces, the Fisher-King. Thus the legends of Jesus and Arthur become somewhat intertwined. After Arthur’s death in 535, the legend of the Holy Grail grew, but it has never been found.
“The stories of King Arthur and his Knights of the Round Table are also fairy tales to all appearance; yet they are based on facts, and pertain to the History of England.” — H. P. Blavatsky, The Secret Doctrine, 2:393
