Perchance was on the blast,
When, through this Height's inverted arch,
Rome's earliest legion passed![CW]
—They saw, adventurously impelled,
And older[280] eyes than theirs beheld,
This[281] block—and yon, whose church-like frame
Gives to this[282] savage Pass its name.[CX]
Aspiring Road! that lov'st to hide
Thy daring in a vapoury bourn,
Not seldom may the hour return
