摘要：The library of the Institute of Historical and Social Sciences of the Croatian Academy of Sciences and Arts in Rijeka has in its safekeeping a publication believed to present the incunabulum published in Venice in 1490, with commentaries by Girolamo Capiduro of Poreč (Hieronymus Capidurus Parentinus) on the work Rhetorica ad Herennium. However, since the Croatian professional literature includes information indicating Girolamo Capiduro had not published the said commentaries before 1550, doubt arose concerning the fact whether the publication kept at the Institute in Rijeka indeed was an incunabulum. The paper has questioned the state of facts and consequently proved that this publication saw the light of day in Venice in 1490. It has furthermore been proved that this was not only the only incunabulum kept at the Institute in Rijeka, but also the only known copy of this publication kept on the Croatian soil. The paper further tackles the issue of the author’s identity, as all the available facts have led to the conclusion that Girolamo Capiduro, as a matter of fact, is a pseudonym of Giorgio Valla, humanist originating from Piacenza.
