Oprawa z superekslibrisami biskupa Erazma Ciołka w zbiorach Biblioteki Raczyńskich w Poznaniu

In 2013 an unknown volume from the collection of books of bishop Erazm Ciołek, an eminent renaissance bibliophile, was discovered in the Raczyński Library in Poznań. The binding of the book features several impressions of a heraldic super ex libris, whereas the lining pasted on the inside of the covers is scrap printing paper from the Jan Haller printing house. In view of an enormous historical value of the volume and scarce knowledge of Ciołek's bibliophilic profile, the binding was set against the other presently known bindings from the bishops' book collection. As a result it was established that he availed himself of the services of the Krakow book binders Piotr Wald and Henryk Sussmund; moreover, he also used at least four kinds of super ex libris, out of which two have a characteristic Italinizing form of the testa di cavallo type. A typographic analysis of the scrap paper revealed that it is probably a fragment of a 'prognostic' that did not survive in any other copy.
