Crouched like two bulls locked horn in horn in fight;
While to the left, a tall scalped mountain ... Dunce,
Dotard, a-dozing at the very nonce,
After a life spent training for the sight!
What in the midst lay but the Tower itself?
The round squat turret, blind as the fool's heart,
Built of brown stone, without a counterpart
In the whole world. The tempest's mocking elf
Points to the shipman thus the unseen shelf
He strikes on, only when the timbers start.
