Boris and Gleb
With Iziaslav's return to Kiev, the "triumvirate" was restored. The three brothers together visited Vyshhorod in order to participate in the translation of the relics of their saintly uncles, Boris and Gleb, on 3 May 1072. According to "The Narrative, Passion, and Encomium of Boris and Gleb", Sviatoslav took Saint Gleb's hand and "pressed it to his injury, for he had pain in his neck, and to his eyes, and to his forehead" before placing it back into the coffin. In short order, Sviatoslav felt a pain at the top of his head and his servant found a fingernail of the saint under his cap. Most historians agree that the three brothers expanded their father's legal code on this occasion, but the exact date is unknown.
