Triumphant cry emanating from Bath? (6)

I believe the answer is:

eureka

'triumphant cry' is the definition.
(I've seen this in another clue)

I can't explain the rest of the clue.

(Other definitions for eureka that I've seen before include "Cry of triumph (at a discovery)" , ""I've found it!" (Archimedes)" , "Triumphant exclamation of discovery" , "Cry announcing a brilliant discovery" , "Bingo!" .)

I've seen this clue in The Times.
