Yaroslav was a notable patron of literary culture and learning. In 1051, he had a Slavic monk, [[Hilarion of Kiev]], proclaimed the [[metropolitan bishop]] of Kiev, thus challenging the Byzantine tradition of placing [[Greeks]] on the episcopal sees. Hilarion's discourse on Yaroslav and his father Vladimir is frequently cited as the first work of [[Old East Slavic]] literature.
