Postil of Jonas Bretkūnas
Postilė (full title: Postilla, tatai esti trumpas ir prastas ischguldimas euangeliu) is a 1000-page postil (collection of sermons and Bible commentaries) written in the Lithuanian language by Jonas Bretkūnas in 1591. It was designed for the purposes of Protestant priests serving Lithuanian communities in East Prussia (territory sometimes known as Lithuania Minor). The book was used until the 18th century. Postilė is one earliest works in Lithuanian that were not merely translations but also included original texts. It contains much ethnographic data about everyday life of the common people. About 30 copies of Postilė survive; 10 of them are kept in Lithuanian libraries and museums.
