The Simple Words of Catechism (Lithuanian: Katekizmo prasti žodžiai) by Martynas Mažvydas is the first printed book in the Lithuanian language. It was printed on 8 January 1547 by Hans Weinreich in Königsberg. The 79-page book followed the teachings of Martin Luther but reflects both religious and secular needs. The book included the first Lithuanian-language poem, primer with alphabet, basic catechism, and 11 religious hymns with sheet music. The book was written in the Samogitian dialect and printed in Gothic (schwabacher) font; Latin dedication and preface are printed in Latin font (antiqua).
