At the entrance to the gateway of the castle were two men made of
copper by art of nicromancy, and they held two great mallets of iron,
and they busied themselves striking the one after the other, and so
strongly they struck that nought mortal is there in the world that
might pass through amongst their blows but should be all to-crushed
thereby. And on the other side was the castle so fast enclosed about
that nought might enter thereinto.
