High Quality Content by WIKIPEDIA articles! The English poet Christopher Smart (1722–1771) was confined to mental asylums from May 1757 until January 1763. Smart was admitted into St Luke`s Hospital for Lunatics, Bethnal Green, London, on 6 May 1757, taken there by his father-in-law, John Newbery, although he may have been confined in a private madhouse before then. While in St Luke`s he wrote Jubilate Agno and A Song to David, the poems considered to be his greatest works. Although many of his contemporaries agreed that Smart was "mad," accounts of his condition and its ramifications varied, and some felt that he had been committed unfairly.
