Castleforge Antiques Ltd has dated this piece to the 1880s.

It was made originally in Britain from a description brought back from Rome in 1504 by Abbot Richard Beere to Glastonbury Abbey, and was produced for or by John Arthur Thorne, a monk who was the treasurer[2] at the abbey. Arthur perished on Glastonbury Tor in 1539, hung, drawn and quartered alongside his master, Richard Whiting, the last Abbot of Glastonbury, during the dissolution of the monasteries. The Abbot sat on a Glastonbury chair during his trial at Bishop's Palace, Wells, where one of the two original surviving examples can still be seen, together with other chairs of this age and later victorian reproductions.

An example of this chair is also in the V & A museum. If you wish further information on the chair please type 'glastonbury chair' into your browser.
