Capital in Asia then, Seoul (6)

I believe the answer is:

athens

'capital' is the definition.
(Athens is an example)

'in asia then seoul' is the wordplay.
'in' says the answer is hidden in the clue.
'ATHENS' is hidden in the letters of 'asia then seoul'.

(Other definitions for athens that I've seen before include "Greek capital" , "City in which 13 Across founded school" , "Hasten to Greek city" , "Hasten to European capital" , "EU capital" .)

I've seen this clue in The Times.
