The Fighting Temeraire artist (6)
I believe the answer is:
turner
'the fighting temeraire artist' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for turner that I've seen before include "potter" , "Popular English artist" , "Artist - wheel?" , "Woodworker and English landscape painter" , "J. M. W. -, English landscape painter" .)
