Nestor's account of the first encounter between the Rus' and the Byzantines may have contributed to the popularity of the Theotokos in Russia. The miraculous saving of Constantinople from the barbarian hordes would appear in Russian icon-painting, without understanding that the hordes in question may have issued from Kiev. Furthermore, when the Blachernitissa was brought to Moscow in the 17th century, it was said that it was this icon that had saved Tsargrad from the troops of the "Scythian khagan", after Michael III had prayed before it to the Theotokos.
