The author of this poem wrote a sequel that promises that the reader shall "know how sublime a thing it is / To suffer and be strong," and states "within my breast there is no light / But the cold light of stars." This poem contains a huge diss against "dumb, driven cattle" in a bivouac doubling as a battlefield. A parody of this poem contains the fantastic line "‘Egg thou art, and egg remainest'/ Was not spoken of the hen." A hypothetical "forlorn and shipwrecked brother" in this poem will be encouraged by the presence of  (*) "footsteps on the sands of time." The speaker of this poem begins "tell me not in mournful numbers" that its subject "is but an empty dream," shortly before yelling "life is real! life is earnest!" For 10 points, name this nauseatingly-affirmatory poem that evokes a widely-sung book of the Old Testament, written by Henry Wadsworth Longfellow.
