What's mere sand is demolished, while the rock

Endures: a column of black fiery dust

Blots heaven—that help was prematurely thrust

Aside, perchance!—but air clears, naught's erased

Of the true outline! Thus much being firm based,

The other was a scaffold. See him stand

Buttressed upon his mattock, Hildebrand

Of the huge brain-mask welded ply o'er ply

As in a forge; it buries either eye

White and extinct, that stupid brow; teeth clenched,
