Engraved by George Zobel, 1864(?)
This somewhat fanciful engraving from the 1800s shows John Wesley surrounded by books and sitting in an apparently elaborately-carved chair.
Interestingly, Wesley's M.A. title ('Master of Arts', or 'Magister Artium', in Latin) is reversed as 'A.M.' This is grammatically correct ('Artium Magister', in Latin) but is hardly ever seen in portraits of John Wesley.
