More about this epigram
Francis Grose (1731-1791) was the son of an immigrant Swiss jeweller, and first met Burns at Friars’ Carse in 1789 when he was collecting pieces for his Antiquities of Scotland (2 vols, 1789-1791).
Burns was impressed by Grose, and in a letter to Mrs Dunlop stated, "I have never seen a man of more original observation, anecdote and remark... His delight is to steal thro’ the country almost unknown, both as most favorable to his humour and his business."
Burns composed this poem after Grose had died in Dublin, collecting material for a proposed work on the antiquities of Ireland.
In this epigram, Burns overtly references the fact that Grose was heavily overweight, so much so that even Satan would think twice about taking him.
