Kiewer Höhlenkloster
During the 1680s, Dimitry lived mostly at the Kiev Pechersk Lavra, while his sermons against hard drinking and lax morals made his name known all over Russia. He was appointed hegumen (superior) of several major monasteries of Ukraine, but concentrated his attention upon the ambitious project of integrating all the lives of Russian saints into a single work, which he published as "Monthly Readings" (Четьи-минеи) or "Menologion" in 1684-1705. He also found time to study ecclesiastical history of the Russian Orthodox Church.
