The exhibition features a number of rarities. This is the first time that Domokos Kálmáncsehi's Breviary, a masterpiece of European book painting, is on display at the National Széchényi Library. János Vitéz's Book of Letters, the primary source of historical information about the age, is displayed in a separate niche. Besides his "everyday codices" filled with notes, the bibliophile archbishop's passion for luxury is reflected by the representative codices, of which the Livy volumes kept in Munich, are introduced. This is the first occasion that the codices of such turbulent history have returned to Hungary since the time that Beckensloer, the archbishop of Esztergom following Vitéz in that position stole them, taking them to Salzburg. The Chronica Hungarorum, the first book printed in Hungary in András Hess's printing house, is a genuine specialty.
