The present paper aims at introducing one of the incu-nabulum from Brukenthal National Museum Library, i.e., Aristotle´s Organon, published in Venice by Baptista de Tordis in 1484. From this perspective, Venice had become the leading centre of book production outside Germany in the fifteenth century, in other words, in the very century of incunabula publication. On the one hand, the work of Syriac scholars in translating and commenting upon Aristotle has been acknowledged as the starting point of the later Arabic-Latin build out. On the other hand, Sergius of Resh´ayna, the author of two related Syriac commentaries on Aristotle´s Categories, was planning to write commentaries on all of Aristotle texts but he seemed to have written nothing beside the Categories before he was overtaken by illness in Constantinople, where he passed away in 536.
