Jefimija (1349–1405), secular name Jelena Mrnjavčević, daughter of Vojihna and widow of Jovan Uglješa Mrnjavčević is considered the first female Serbian poet, famous in Serbian medieval literature are her Lament for a Dead Son and Encomium of Prince Lazar. The laments, a strictly feminine form of lyric, is common to some Slavic languages (called tuzhbalice in Serbian), and long narrative laments are intimately connected with heroic epics (example, Yarsolavna's lament in the The Tale of Igor's Campaign).
