God of peace? (4)

I believe the answer is:

odin

I'm a little stuck... Click here to teach me more about this clue!

'god' is the definition.
(Norse god)

'of peace?' is the wordplay.
'of' becomes 'o''.
'peace?' becomes 'din' (I am not sure about this - if you are sure you should believe this answer much more).
'o'+'din'='ODIN'

Can you help me to learn more?

(Other definitions for odin that I've seen before include "Legendary Scandinavian" , "divine figure" , "Chief god of Scandinavian myth" , "Chief Norse god" , "Mythological Norse deity" .)

I've seen this clue in The Telegraph.
