The testament of the Hungarian calligrapher George Bocskay (†1575) has been recently discovered in the Archive of the Benedictine Archabbey of Pannonhalma. Bocskay made his will on the 4th of April 1575, in the house of the Hungarian magnate János Pethő de Gerse (III) in Vienna. The original document published here was written in Latin. The new data provided by the testament are of primary importance regarding the life and social network of George Bocskay. According to the text he left his property to his wife and children as well as his four servants, among others he bequeathed his books and instruments of calligraphy to his son, Stephen. His burial place was unknown yet. However, in his testament Bocskay ordered to be buried in the Himmelpfortkloster in Vienna. It was a significant medieval Premonstratesian cloister, founded for nuns by Constance of Hungary, the daughter of the Hungarian King Béla III, in the 1230s.
