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 found in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?
