Lysons in his "Environs of London," says, "In a room adjoining to the
south-side of the saloon, in the manor-house, at Charlton, in Kent, is
a chimney-piece, with a slab of black marble so finely polished, that
Lord Downe is said to have seen in it a robbery committed on Blackheath;
the tradition adds, that he sent out his servants, who apprehended the
thieves." Dr. Plot makes the story more marvellous, by laying the scene
of the robbery at Shooter's Hill; he also says, "Thus in a chimney-piece
at Beauvoir Castle, might be seen the city and cathedral of Lincoln, and
in another at Wilton, the city and cathedral of Sarum."
