(roughly, "company") in permanent warfare against neighboring states. According to the Primary Chronicle, he carried neither wagons nor kettles on his expeditions, and he boiled no meat, rather cutting off small strips of horseflesh, game, or beef to eat after roasting it on the coals. Nor did he have a tent, rather spreading out a horse-blanket under him and setting his saddle under his head, and all his retinue did likewise. Sviatoslav's appearance has been described very clearly by Leo the Deacon, who himself attended the meeting of Sviatoslav with John I Tzimiskes. Following Deacon's memories, Sviatoslav was a bright-eyed man of average height but of stalwart build, much more sturdy than Tzimiskes. He had a bald head and a wispy beard and wore a bushy mustache and a sidelock as a sign of his nobility. He preferred to dress in white, and it was noted that his garments were much cleaner than those of his men, although he had a lot in common with his warriors. He wore a single large gold earring bearing a carbuncle and two pearls. Religious beliefs Sviatoslav's mother, Olga, converted to Orthodox Christianity at the court of the Byzantine Emperor Constantine Porphyrogenitus in 957, at the approximate age of 67. Sviatoslav remained a pagan all of his life. In the treaty of 971 between Sviatoslav and the Byzantine emperor John I Tzimiskes, the Rus' swore by the gods Perun and Veles. According to the Primary Chronicle, he believed that his warriors (druzhina) would lose respect for him and mock him if he became a Christian. The allegiance of his warriors was of paramount importance in his conquest of an empire that stretched from the Volga to the Danube. Family Very little is known of Sviatoslav's family life. It is possible that he was not the only (or the eldest) son of his parents. The Rus'-Byzantine treaty of 945 mentions a certain Predslava, Volodislav's wife, as the noblest of the Rus' women after Olga. The fact that Predslava was Oleg's mother is presented by Vasily Tatishchev. He also speculated that Predslava came from the Hungarian nobility. George Vernadsky was among many historians to speculate that Volodislav was Igor's eldest son and heir who died at some point during Olga's regency. Another chronicle told that Oleg (? - 977?) was the eldest son of Igor. At the time of Igor's death, Sviatoslav was still a child,
