God posed beside vase (6)
I believe the answer is:
saturn
'god' is the definition.
(Saturn is an example)
'posed beside vase' is the wordplay.
'posed' becomes 'sat' ('sit' can be a synonym of 'pose').
'beside' means one lot of letters go next to another (I've seen this in other clues).
'vase' becomes 'urn' (urn is a kind of vase).
'sat'+'urn'='SATURN'
(Other definitions for saturn that I've seen before include "The second largest planet" , "Nearest ringed planet" , "Giant planet" , "Runs at (anag) - Roman god" , "Sixth planet from the sun" .)
