This author that praised sleep as a "soft embalmer of the still midnight," wrote a poem addressed to Thaddeus Koscuisko.  The phrase "That ancient Beardsman hear the prelude soft," appears in a stanza about Porphyro and [?] Madeline running away. Another poetic work is about a demon revealed to be a snake after being made visible by Hermes. In another poem, this man that imagined "when a new planet swims into his ken," surmised "bards in fealty to Apollo hold," in a work where the narrator had "travell'd in the realms of gold." In another work, this poet wrote about seeing "pale kings and princes too," and even though the title person "hath thee in thrall." For ten points, name this man who looked into Chapman's translation of Homer and wrote La Belle Dame Sans Merci.
