Since this campaign is not recorded in Greek sources, historians have suggested that the account actually refers to the events of the Rus'–Byzantine War (1043) and to a different Vladimir. In fact, most valuables looted by the Slavs in Korsun' made their way to Novgorod (perhaps by way of Joachim the Korsunian, the first Novgorodian bishop, as his surname indicates ties to Korsun), where they were preserved in the Cathedral of Holy Wisdom until the 20th century. One of the most interesting items from this "Korsun Treasure" is the copper Korsun Gate, supposedly captured by the Novgorodians in Korsun' and now part of the St. Sophia Cathedral.
