From the Prologue of Ochrid
Persecuted by his relatives, he left the world and was tonsured a monk. The Kievans, dissatisfied with the Olgovichi dynasty, wished to exterminate it. They rushed upon the monastery, seized the innocent and young schema-monk Igor, and slew him. Because of this crime many calamities befell the Kievans. And at the tomb of this blessed one candles were seen, lit of themselves, on several occasions, and over the church where he was buried a pillar of fire was seen. This was in the year 1147.
