He'll exorcise
The walls that rise
With turrets square
From rocks so bare.
Its front looks to the setting sun,
And over the windows one by one—
Lest demon ever through them may pass—
He carves his mitre over the glass."[2]
To this demon-proof stronghold the Bishop appoints a warder, who—as is the way of warders—has a charming daughter, Mourrette. Mourrette has a lover who is determined to scale the walls of the fortress and carry off the damsel or die in the attempt. Unfortunately, he dies in the attempt.
