Rainbow

If, then, to meanest mariners, and renegades and castaways, I shall hereafter ascribe high qualities, though dark; weave round them tragic graces; if even the most mournful, perchance the most abased, among them all, shall at times lift himself to the exalted mounts; if I shall touch that workman’s arm with some ethereal light; if I shall spread a rainbow over his disastrous set of sun; then against all mortal critics bear me out in it, thou just Spirit of Equality, which hast spread one royal mantle of humanity over all my kind!

And how nobly it raises our conceit of the mighty, misty monster, to behold him solemnly sailing through a calm tropical sea; his vast, mild head overhung by a canopy of vapor, engendered by his incommunicable contemplations, and that vapor—as you will sometimes see it—glorified by a rainbow, as if Heaven itself had put its seal upon his thoughts. For, d’ye see, rainbows do not visit the clear air; they only irradiate vapor. And so, through all the thick mists of the dim doubts in my mind, divine intuitions now and then shoot, enkindling my fog with a heavenly ray.
