Despite being Montenegro's ruler for more than twenty years, Njegoš is best known for his literary output. His writings drew on Serb folklore, lyric poetry and biblical stories. He began writing poetry at the age of seventeen, and his literary opus includes "Glas kamenštaka" (The Voice of a Stone-Cutter; 1833), "Lijek jarosti turske" (The Cure for Turkish Fury; 1834), "Ogledalo srpsko" (The Serbian Mirror; 1835), "Luča mikrokozma" (The Ray of the Microcosm; 1845), "Gorski vijenac" (The Mountain Wreath; 1847), "Lažni car Šćepan mali" (The False Tsar Stephen the Little; 1851) and, posthumously, "Slobodijada" (The Freedom Song; 1854). His most famous works are "Luča mikrokozma", "Gorski vijenac" and "Lažni car Šćepan mali", all epic poems.
