Head-and-shoulders plaster bust of Adam Duncan after Sir Richard Westmacott's monument to the sitter in St Paul's Cathedral. It shows him facing slightly to his right in admiral's full dress of 1795-1812, with the star and sash of the Bath and the flag officers' naval gold medal for Camperdown hanging on a ribbon round his neck.

The bust is one of a set of four (see also SCU0031, SCU0032, and SCU0085) made in 1809 for the architect Daniel Asher Alexander for the Royal Naval Asylum at Greenwich, which Alexander was then constructing (1807-10) around the Queen's House.

He was encouraged to employ Chantrey by James Montgomery, whose portrait Chantrey had just painted. All four busts have usually been presumed to be copies from works by others. This one of Duncan was shown at the Royal Academy in 1809, apparently with those of Howe and St Vincent.

As indicated above, Chantrey was a painter before he became a sculptor and this set of plaster busts for the Royal Naval Asylum is one of his earliest sculptural commissions.
