Christopher Smart, an accomplished English poet, was recognized for his rich and fervent expressions of faith and emotion in his works, particularly the poem 'Jubilate Agno,' which he wrote during his period of confinement. Born in 1722, Smart's life was marred by episodes of mental instability that eventually culminated in his admission to St Luke's Hospital for Lunatics in London. This hospital, infamous for housing individuals with severe mental health issues, marked the beginning of a six-year period wherein Smart would be confined in various asylums. Reports suggest that his condition and lifestyle choices, including financial mismanagement and his relationship with his family, contributed significantly to his mental health deterioration. His admission to St Luke's was part of a larger societal context where individuals suffering from mental illness were often institutionalized, with limited understanding or effective treatments available at the time.

During his confinement, Smart created a wealth of poetry, showcasing his intellectual depth even amid his struggles. His work often explored themes of divinity, nature, and the human condition, revealing not only his brilliance as a poet but also the complexities of his mental state. 'Jubilate Agno' is notable for its structure, combining various biblical references with personal reflections, illustrating a desire for spiritual connection even in despair. Throughout his time in the asylums, Smart experienced a mix of compassion and cruelty, reflecting broader societal attitudes toward mental illness in 18th-century England. Despite the challenges faced during these years, Smart's legacy as a poet endures, providing insight into the intersection of creativity and mental health.
