The emperor took the oath upon the evangelists.

Oleg swore by his sword and the gods of Russia.

In token of his triumph Oleg proudly raised his shield, as a banner, over the battlements of Constantinople, and returned, laden with riches, to Kief, where he was received with the most extravagant demonstrations of adulation and joy.
The treaty thus made with the emperor, and which is preserved in full in the Russian annals, shows that the Russians were no longer savages, but that they had so far emerged from that gloomy state as to be able to appreciate the sacredness of law, the claims of honor and the authority of treaties.

It is observable that no signatures are attached to this treaty but those of the Norman princes, which indicates that the original Sclavonic race were in subjection as the vassals of the Normans.

Oleg appears to have placed in posts of authority only his own countrymen.
Oleg now, as old age was advancing, passed many years in quietude.
Surrounded by an invincible army, and with renown which pervaded the most distant regions, no tribes ventured to disturb his repose.
