But if you spit on his marker, too bad, he ain't there no more. Nobody's there, the horse is out and the stable door is open.
After the Restoration the royalists dug the man's body out of his grave in Westminster Abbey, hanged him, cut off his head, and stuck the head on a pole at Westminster where it remained for 20 years. It blew down in a storm, and one of your typical English eccentrics kept it under his sofa for a long time. It passed from owner to owner, but some time in the 50s it was X-rayed and they decided it was really Cromwell's. Eventually the head wound up at Cambridge and was buried in an unmarked location near Sidney Sussex college. The body is, I presume, still under the old location of Tyburn Tree (near Connaught Square).
. . . they really knew how to hold a grudge in the good old days . . .
