John of Glastonbury
John of Glastonbury was a Benedictine monk and chronicler. His real name may have been John Seen.
In the mid fourteenth century John wrote the Cronica Sive Antiquitates Glastoniensis Ecclesie which is a chronicle of Glastonbury Abbey, from when it was founded, up to the period of John's life. The Cronica survives as a full text over seven manuscripts. The Cronica refers to the Arthurian legends several times, and John drew extensively on De Antiquitate Glastonie Ecclesie by William of Malmesbury.
