John Wharlton Bunney (20 June 1828 – 23 September 1882) was an English topographical and landscape artist of the nineteenth century.
The couple settled in Florence; they had four children, including the Hampstead Garden Suburb architect, Michael Bunney.
Ruskin said that Bunney's work was "so faithful and careful as almost to enable the spectator to imagine himself on the spot."
(Ruskin was campaigning to prevent a renovation of the west front of St. Mark's, and the painting was part of this effort.)
After Bunney died in 1882, Ruskin started a memorial fund to benefit his widow and children.
