Katechysmus, To geʃt: Kratičke obʃazenij a wyklad přednich Cžlankůw Wyrij a Náboženʃtwij Křestianského čemuž ʃe Lidé Křestianʃʃtij a zwlaʃʃte Dijtky w Sʃkolách počátečné wyvčugij (Catechism, that is: a brief overview and an exposition of the foremost articles of faith and the Christian religion, which catechumens, and especially children in schools, learn initially), published in 1581, is the first work printed in the territory of Slovakia in the Slovak language. It is the famous “small catechism” by Martin Luther (1483−1546), the great leader of the Protestant Reformation in Germany. The book was produced in Bardejov, in the print shop of David Gutgesel (1540–99). Gutgesel was born in Bardejov and lived and worked in the town virtually his entire life. A printer, publisher, and bookseller, he founded his printery in 1577. Over the course of the next 20 years he printed approximately 80 titles, all now very rare, including, for example, some of the works of the Slovak poet and scholar Ioannes, or Ján Bocatius (1569–1621).
