Kit Smart was a religious poet who died in debtor’s prison, aged 49, in 1771.
Most controversially, in 1757, his father-in-law took Smart against his will to be committed to a lunatic asylum. There he wrote his now-famous poem Jubilate Agno (“Rejoice in the Lamb”), although the poem was not published until 1939.
It contains these evocative lines:
For the bite of an Adder is cured by its greese and the malice of my enemies by their stupidity.
