Portrayed wise man with hidden identity? Quite the opposite (6)
I believe the answer is:
imaged
'portrayed' is the definition.
'wise man with hidden identity? quite the opposite' is the wordplay.
I cannot really see how this works, but
'man' could be 'mage' (I have seen 'Wise man' mean 'mage' so perhaps 'man' could also mean 'mage') and 'mage' is present in the answer.
'identity?' could be 'id' (abbreviation) and 'id' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for imaged that I've seen before include "shown in picture" , "Formed a picture of" , "Fancied" , "Copied" .)
