For the record : How many times did Rome sack Ctesiphon ?

[hoplite14gr]

If... Sebeos. History. trans. Robert Bedrosian (New York: Sources of the Armenian Tradition, 1985), 106-107, 113-116 ....is to be belived ,Heraclios after the battle of Ninevi only sent envoys to Ctesiphon to recover the Holy Cross but he and his army did not enter the city probably to avoid getting involved in Iranian civil war and because the restoration of the cross to Jerusalem would make the people forget theit resentment for his marriage with Martina.
Kind regards
