God of youth, originally? (4)

I believe the answer is:

thor

'god' is the definition.
(Thor is an example)

'of youth originally?' is the wordplay.
'of' indicates the answer is hidden within the clue.
'THOR' can be found hidden inside 'youth originally'.

(Other definitions for thor that I've seen before include "Norse hammer-wielding god" , "Comic superhero" , "Norse god of war" , "Norse deity" , "Scandinavian thunder-god" .)

I've seen this clue in the Evening Standard.
