The grave of the poet Robert
Fergusson (1750-1774) is in the churchyard of Canongate Kirk in Edinburgh. Fergusson is considered the inspiration of Robert Burns.
According to the Wikipedia entry "Burns was the first to pay tribute
to the merits of Fergusson; on his visit to Edinburgh in 1787 he sought
out the poet's grave, and petitioned the authorities of the Canongate
burying-ground for permission to erect the memorial stone which is
preserved in the existing monument. The date there assigned for his birth
differs from the one given above, which rests on the authority of his
younger sister Margaret". Burns wrote the inscribed poem.
