Scene in play about Greek maiden (7)
I believe the answer is:
diorama
'scene' is the definition.
(thesaurus)
'play about greek maiden' is the wordplay.
'play' becomes 'drama' ('drama' can be a synonym of 'play'**).
'about' indicates putting letters inside.
'greek maiden' becomes 'io'.
'drama' going around 'io' is 'DIORAMA'.
'in' acts as a link.
(Other definitions for diorama that I've seen before include "Miniature three-dimensional scene" , "Three-dimensional series of pictures representing a scene" , "Model showing a scene" , "Miniature 3-D scene -- or a maid (anag)" , "picture that has depth" .)
