Has it now been established that Shakespeare was actually a living person?
From memory, so may not be quite right, but I believe his grave marker was inscribed with this verse by him:
Good friend for Jesus’ sake forbear
to dig the dust enclosed here
Blest be he who spares these stones
and cursed by he who moves these bones...
They’ll dig and find a plaque with a list of names on it. Two of the names on it will be Dr. Faust from Germany and Robert Johnson from Mississippi. You can guess the rest.
