Hands, that the rod of empire might have swayed,

Or waked to ecstasy[658] the living lyre.[659]

13. But Knowledge to their eyes her ample page,

Rich with the spoils of time, did ne’er unroll;

Chill Penury[660] repressed their noble rage,

And froze the genial current of the soul.

14. Full many a gem, of purest ray serene,

The dark, unfathomed caves of ocean bear;

Full many a flower is born to blush unseen,

And waste its sweetness on the desert air.
