full_question: In a poem by this man, a group appears at first "like the leaves of the forest when Summer is green" but then "when Autumn hath blown." That poem by this man describes a rider lying "distorted and pale / With the dew on his brow, and the rust on his mail." This poet also described a woman with "a mind at peace with all below." This man wrote a poem in anapestic tetrameter to evoke the galloping of horses, in which attackers' spears are likened to "stars on the sea" but become useless after "the Angel of Death spread his wingsÂ…and breathed in the face of the foe." For 10 points, name this poet who wrote about an Assyrian king who "came down like the wolf on the fold" in "The Destruction of Sennacherib" and about a woman who moves "like the night" in "She Walks in Beauty."
