attack upon Kiev", stating that "if he intended to nurse his wrath and destroy the city, they would be properly concerned for the ancestral capital". Iziaslav partially acquiesced: he did not let his Polish allies enter the town, but his retinue slaughtered or mutilated many of his opponents in Kiev. He also attempted to punish Anthonythe founder of the Monastery of the Caves in Kievwho had supported his enemies, but Sviatoslav gave shelter to the saintly monk in Chernigov. 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.

In fact, the Primary Chronicle states that it was Sviatoslav who "ruled in Kiev after the expulsion" of Iziaslav. Initially, the head of the Monastery of the Caves, Feodosy criticized Sviatoslav for usurping the throne. However, before his death in May 1074 he was reconciled with the grand prince,
