Paisius Yaroslavov was a prominent 15th-century ascetic monk and writer associated with the Kamenny Monastery. Living during the reign of Ivan III, he held significant influence within the Grand Principality of Moscow, serving as a hegumen at the Troitse-Sergiyeva Lavra between 1478 and 1482. Due to his reputation for virtue and learning, he acted as a tutor to the grand prince's children and provided theological counsel to high-ranking clergy, including Archbishop Gennadius of Novgorod.
