How oft,—be witness, Guardian of our days!... The sky besprinkled o'er with rainbow hues, As if angelic wings had wanton'd there;...

The speaker addresses a divine “Guardian of our days,” invoking God as witness to repeated moments of awe before nature. The “sky besprinkled…with rainbow hues” suggests a sunset or storm-cleared firmament whose colors are read as signs of the supernatural. By imagining the hues as traces of “angelic wings,” the lines exemplify a Romantic-evangelical habit of interpreting natural beauty as evidence of a spiritual realm and of providential care. The exclamation and apostrophe (“be witness”) frame the scene as devotional recollection: the outward spectacle becomes an inward testimony of faith, gratitude, and the longing to see the divine in the visible world.
