Severely criticise article on Roman temple (8)
I believe the answer is:
pantheon
'roman temple' is the definition.
(The pantheon is a roman temple)
'severely criticise article on' is the wordplay.
'severely criticise' becomes 'pan' (pan can mean to criticise heavily).
'article' becomes 'the' (the definite article in English).
'pan'+'the'+'on'='PANTHEON'
(Other definitions for pantheon that I've seen before include "Circular temple in Rome" , "All the gods of a people or religion" , "Hall of fame" , "Temple of all the gods in ancient Greece" , "church" .)
