A characteristic of these "cage elevators" was that the doors (or the gates) must be closed manually for them to be "called" to another floor.
One day one of the workers, Peter by name, took the elevator to the top floor, and it was subsequently needed on the first floor by the sexton. Unfortunately, Peter forgot and left the door open.
After the sexton rang for the elevator a couple times, to no avail of course, and he yelled up for the worker to send the lift back down. Visitors to the cathedral were treated to this sight: The sexton of the cathedral, head tipped up, yelling up to the heavens:
"PETER! CLOSE THE GATES!!!"
