A set of 56 small plates of natural history engraved by Mitan, perhaps from his own designs, was published in 1822. Between 1802 and 1805 he exhibited a series of compositions illustrating George Moore's gothic novel Theodosius de Zulvin at the Royal Academy, and in 1818 showed a design for a national memorial of the battle of Waterloo. In 1818 he also made a design, 18 feet long, for a chain bridge over the River Mersey. Mitan worked for the Admiralty and the Freemasons. A plate of Charles Robert Leslie's 'Anne Page and Slender,' which Mitan left unfinished, was completed by Francis Engleheart and published in 1823.
