Ancient city, source of history in times of horse-drawn transport? (8)
I believe the answer is:
carthage
'ancient city' is the definition.
(I've seen this before)
'source of history in times of horse-drawn transport?' is the wordplay.
I cannot really understand how this works, but
'horse' could be 'cart' (cart horse is a kind of horse) and 'cart' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for carthage that I've seen before include "It fought the Punic wars against ancient Rome" , "Old African city" , "Ancient Tunisian city" , "Hannibal's home city" , "Ancient N. African city" .)
