Thus error's monstrous shapes from earth are driven;
They fade, they fly--but Truth survives their flight;
Earth has no shades to quench that beam of heaven;
Each ray that shone, in early time, to light
The faltering footstep in the path of right,
Each gleam of clearer brightness shed to aid
In man's maturer day his bolder sight,
All blended, like the rainbow's radiant braid,
Pour yet, and still shall pour, the blaze that cannot fade.
