The oldest printed book in Serbian-Slavonic was first issued in 1483, from the printing-press of "Andreas Torresanus, de Asula" (1451–1529) in Venice. A few years later the Serbian nobleman Božidar Vuković bought a printing-press in Venice and established it at Obod in Montenegro, from which he issued in 1493 the first church book—the "Oktoih"—printed on Serb territory. There is a copy of this book in the British Museum. Vuković's printing press operated in two phases. In the first one (1519–20), he printed "Služabnik" (1517) and "Psaltir sa posledovanjem i časlovcem" (Psalter, 1520). In the second phase (1536–40), which came after a long break, he published five more books in Serbian Cyrillic: "Zbornik" (1536), "Molitvenik" (Prayer book, 1536), "Oktoih petoglasnik" (1537), "Minej" (The Book of Months, 1538), "Molitvenik trebnik" (1539 or 1540). All of his editions are printed versions of liturgical works in Serbian redaction of Church Slavonic that have long been in use in the Serbian Orthodox Church. In addition to remedying the of Serbian books, he also wanted to produce books which were printed in smaller letters, making them more compact and easier to carry. His editions were intricately prepared, with well-proportioned letters and fine miniatures. Vuković collaborated with other Serb refugees in Venice such as hieromonk Pahomije from Rijeka Crnojevića in Montenegro ("ot Crne Gori" or "Reki"), hierodeacon Mojsije of Budimlje ("ot serbskije zemlji, otčstvom že ot mjesta naricamego Budimlja") and priests Teodosije and Genadije from the Mileševa monastery. Vuković was a ktitor of the Mileševa monastery.
