Robert Browning praised this author for having “pierced the screen 'twixt thing and word” in a poem that relates a story of this author carving one of his poems into the wainscot with a key. A poem by this author was finally published in 1939 after its manuscript was discovered by W. F. Stead. This poet's The Hop-Garden was panned by John Hill, who this man then mocked in The Hilliad. Antiphonal Hebrew verse inspired a 1200-line poem by this man in which many lines beginning with the word “let” are paired with lines beginning with the word (*) “for.” An oft-excerpted section of that poem by this man describes a “servant of the Living God” as a “mixture of gravity and waggery” who is “of the tribe of Tiger.” For 10 points, name this poet who praised his cat Jeoffry (-5[2])in Jubilate (10[1])Agno, which he wrote in a mental asylum. ■END■ (10[1])
