It seems that Mark, in talking of 1100AD is remembering the Rufus Stone which marks the spot where stood an oak from which an arrow glanced (!?) and killed William Rufus (King William 2nd).Rufus was so much hated for his draconian Forest Laws that he was probably murdered.His body, ". . . was laid in a cart, belonging to one Purkis, and drawn from hence, to Winchester, and buried in the Cathedral Church, of that City.".I expect Purkis thoroughly enjoyed the journey and was given free beer, board and lodging at every hostelry!
I have pictures of the stone and if you, or anybody else, would like the .jpeg images, contact me direct
