James Malton moved with his family to Dublin in 1785, where his father, Thomas Malton (1726-1801), an architectural draftsman, taught perspective. James worked for several years in the office of the distinguished architect James Gandon (1742–1823), before returning to London in 1790, where he exhibited topographical and architectural drawings at the Royal Academy. Malton published two sets of views of Dublin engraved by himself – the first, A Descriptive View of Dublin, in 1797. The second was published posthumously in circa 1818 and included both drawings from the first edition, and later ones.
Another watercolour by Malton of St Patrick's Cathedral, dated to circa 1797, is now in the Victoria and Albert Museum, London (172-1890).
