Portrait of Gloucestershire, T A Ryder

abbreviated.......

'Flaxley - When the monastic houses were dissolved, Henry VIII sold the abbey to Sir William Kingston in 1537, three years later is passed to his son Anthony, who sold it to the Boevey family, London merchants, and they lived in the part of the abbey that had been converted into a dwelling houses .... Undoubtedly, the most interesting of the Boeveys is Catherine, the young wife of William Boevey, whom she married in 1687....... She entertained many of the literary figures of the day at the Abbey, including Pope, Steel and Addison. .... included in her will was a bequest to build a chapel at Flaxley. This was done by her great friend and Executrix, Mrs Mary Pope (the Boevey Chapel). Mrs Pope's name has been remembered in a local place-name. It came about like this; Mrs Pope was invited to come and stay for a fortnight at the abbey; forty years later, when Mrs Boevey died, she was still there. Her favourite walk was over a hill near the abbey from which a magnificent view of the Horse-shoe Bend of the Severn and the distant Cotswolds can be obtained; local folk re-named the hill Pope's Hill to commemorate such a lengthy visit'

Think this is Alexander Pope (as it talks about Richard STEELE and Joseph ADDISON)
