On Joseph’s last visit to England he took his boat around the tip of Cornwall and landed in Wales. Driven eastward by hostile Druids, he and his party acquired a benefactor in the form of a local king, who gave the small band of Christians an island called Ynys-witrin: the Glassy Isle, or Glastonbury.[2] The Glastonbury Tor (Tor means hill) was in these times not a giant hill but an island surrounded by water and marsh.
A miracle occurred on a smaller hill near the Tor, Weary-all Hill. While preaching to the locals Joseph struck his staff into the ground. Was he emphasizing a point, expressing exasperation, or praying for a miracle to convert the souls of the Celtic Druids? Whatever his motive, when Joseph’s staff hit the ground leaves and blossoms shot forth from the wood.
On that spot, veiled by the mist of antiquity, grew a huge, double trunked tree that sported white blossoms each Christmas. Known as the Hawthorn Tree, or the Glastonbury Thorn, the flowering Hawthorn fascinates botanists even today. A plant of middle Eastern origin that blooms every Christmas in a cold climate has proved impossible to explain, at least by natural means. And why did the miraculous tree exist in Glastonbury alone? More than one Puritan tried to answer this question with the blade of an axe.[3]
English author J.R.R. Tolkien was familiar with the Glastonbury legends, which included the tales of King Arthur. A literary legend, Arthur was also an actual man who trod the same hallowed ground as Joseph of Arimathea.
It happened in 1193, during the reign of Henry II, six centuries after Arthur’s death.[7]Sixteen feet below the floor of the Glastonbury Abbey was found a huge, hollowed out log, a common burial custom among Celtic Britons. Engraved letters on a leaden cross identified the remains as that of Arthur and his wife Guinevere.[8] Arthur’s skeleton was enormous, and his skull showed the effects of ten wounds. Strands of plaited golden hair on the smaller skeleton turned to powder under the fingers of a curious monk. Arthur’s famous sword, Excalibur, passed to Henry II’s son, Richard the Lion-Hearted, who took it with him when he left England on his Crusade.[9]
From the location of Arthur’s tomb it is evident that the Isle of Avalon was really the Isle of Glastonbury. Another interesting coincidence is Arthur’s quest for the Holy Grail, the chalice used by Christ at the Last Supper. Usually dismissed as literary fancy, Arthur’s quest for the Grail in the same area inhabited by Joseph of Arimathea is at least logical, for it is said that Joseph brought the Grail with him to England.[10]

[2] Why it was called Ynys-witrin, or the Isle of Glass, is unclear. It may have to do with the appearance of the water that surrounded the island, or with an old Druid legend that the area was an entrance to the Celtic underworld, a passage that went through a druidic palace of glass.

[9] Williamson, p. 50. The Glastonbury Abbey was at the time the most famous Christian landmark in Britain. It was destroyed by fire and restored by Henry II. Arthur and Guinevere’s relics were solemnly deposited in a large tomb in the restored Abbey. Four centuries later the Abbey and the tomb were destroyed by the Reformers.
[10] This is a later tradition that developed after Arthur’s remains were found. Although the Church has never endorsed the tradition that Joseph brought the Chalice of the Last Supper with him to England, an older and more generally accepted tradition is that Joseph brought with him 2 small cruets containing the Precious Blood, which he collected while removing Christ from His Cross. The cruets, and wooden staffs representing the Glastonbury Thorn, appear on Joseph’s coat of arms.
