God Michelangelo himself captures (6)
I believe the answer is:
elohim
'god' is the definition.
(I've seen this before)
'michelangelo himself captures' is the wordplay.
'captures' indicates the answer is hidden within the clue (the answer is trapped within the clue).
'ELOHIM' can be found hidden inside 'michelangelo himself'.
(Other definitions for elohim that I've seen before include "deity" , "Hebrew name for God" , "Artificer, for some" , "A Heb. name for God" .)
