Борис и Глеб
While returning from his victory, Igor visited the shrine of SS. Boris and Gleb in Vyshgorod (today "Vyshhorod" in Ukraine) to celebrate their feast. There he met with Roman I Rostislavich of Kiev (his brother-in-law) and his brothers on July 25. Their meeting was political in nature in that Igor would have pledged allegiance to the new ruler of Kiev.
