Worship of sacred figures, i.e. holy art, possibly about right (10)

'worship' is the definition.
(hierolatry is a kind of worship)

'of sacred figures i e holy art possibly about right' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is found in the answer.
'i' could be 'a' and 'a' is found in the answer.
'e' is present in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
