Board has gold representation of a historical scene (7)
I believe the answer is:
tableau
'representation of a historical scene' is the definition.
'tableau' can be an answer for 'scene' (I've seen this in another clue). I'm not certain of the 'representation of a historical' bit.
'board has gold' is the wordplay.
'board' becomes 'table' (both can mean food).
'has' means one lot of letters go next to another.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'table'+'au'='TABLEAU'
Can you help me to learn more?
(Other definitions for tableau that I've seen before include "Staged scene" , "Group of people arranged as for a painting say" , "pictorial presentation" , "still life?" , "Motionless figures representing a scene" .)
