Unus non sufficit orbis – One world is not enough: Hungarian Jesuits in South America

On the occasion of the 300th anniversary of the birth of György Pray, the father of Hungarian critical historiography and former director of our library, and the 250th anniversary of the abolition of the Jesuit order, we invite you to an exhibition of documents related to the missions of the Hungarian Jesuits in South America.

The exhibition offers visitors a special selection of manuscripts and printed documents. The South American continent was one of the main scenes of the Jesuit Order's flourishing in the 18th century. It was one of the most important places where the most enthusiastic and adventurous members of the Jesuit Order, including Jesuits of Hungarian origin, carried out their missionary work. If you want to know what adventures the friars had in the depths of the jungle, how they canoed down the Amazon or what experiences they had among the Indians, visit our exhibition! 

The exhibition is available on weekdays between 10.00 and 15.00. Registration is possible at

Adopt this book in September!

Ferenc Menyői Tolvaj (c. 1649–1710) published his first work in Debrecen in 1674, which he called ‘The Mastery of Arithmetic’. From the first edition it was taught in the arithmetic classes of the Debrecen Reformed College. Several further editions were published in the 18th century, for example in Bratislava (1727) and in Levoča (1729).

In his foreword, Tolvaj indicates that his book is intended primarily for students who can read Hungarian and for people working in commerce. It is relatively limited in content, as it deals only with the four basic arithmetic operations and does not mention fractions, but it can still be used as a coursebook for elementary education. Its language is not particularly revolutionary either, since it uses Latin equivalents of established Hungarian mathematical terms. However, his work can be entertaining for younger students, as he presents the rules of arithmetic in verse. One of his 18th-century critics, György Maróthi (1715–1744), a professor in Debrecen, also found that Menyői’s book is lacking more complex calculations, adding that he thought the ’whole work was very silly [...] and boring’, noting that Menyői himself did not seem to understand arithmetic. The present copy was once owned by Ferenc Kenesei, as attested by his ownership record: Sum Kenesei Francisci

The book is part of the book adoption program of the Foundation for the University Library. Save a book, adopt a book! For more information visit our website:

Buda Chronicle 550

On the occasion of the 550th anniversary of the Buda Chronicle, our temporary exhibition offers an insight into the original version of the Chronica Hungarorum and the most unique publications in the history of printing.

The most famous publication of the first printing house in Hungary is the Chronica Hungarorum (Buda Chronicle), produced by András Hess for the eve of Pentecost on the 5th of June 1473, the original version preserved in our library is also notable for the fact that the edition never left the territory of historic Hungary.

In our country, however, the printing of books could not take root for a long time due to the lack of a suitable patron. A few years later, presumably also in Buda (possibly Bratislava), between 1477 and 1480, another press, the Confessionale printing house, renowned for its first edition, may have been in operation. The printing house's products, the Confessionale by the Florentine Archbishop Antoninus Florentinus and the 15th century Johannine unique biography of St. Jerome by Laudivio Zacchia, are also on display.  

Later, over several decades, the special historical works presented in our exhibition were selected from foreign workshops, including the Thuróczy Chronicle, the Schedel Chronicle with a view of Buda, and the chronicle of the German theologian Johann Ludwig Gottfried, depicting the execution of László Hunyadi.

The chamber exhibition is open until the 8th of September 2023, from 10.00 to 15.00 on weekdays. Registration is possible at More information about our exhibitions is available on our website.
