No More Learning

XI
This while, as here and there in fruitless pain
He moves, oppressed with thought and trouble sore,
Gradasso, Brandimart, and him of Spain,
Ferrau, he finds, with           and more;
Who ever toiling, like himself, in vain
Above, that building, and beneath explore,
And as they wander, curse with one accord
The malice of the castle's viewless lord.
