Gallery idols (4)
I believe the answer is:
gods
I believe this is a double definition.
'gallery' is the first definition.
(I've seen this in other clues)
'idols' is the second definition.
('god' can be a synonym of 'idol')
(Other definitions for gods that I've seen before include "Deities" , "Area of theatre" , "Idols" , "Superhuman beings" , "high up in theatre" .)
