No copies in public collections (OCLC), recent public sales or bookstores. Very rare publication by the Greek printer Dimitrios Theodosiou, from a large merchant family from Ioannina who settled in Venice in the 17th century. After working as a printer's apprentice in the workshop of Nikolaos Glykis (another printer of Greek origin settled in Venice) and taking over the management of the printing house in 1745, he opened his own bookshop. In 1755, he obtained the authorization to found a Greek printing house, with the obligation to print books in Slavic, for the benefit of the Slavic-speaking populations of the Balkans. His nephew Andreas joined him in the printing house. At that time, the printing house had commercial relations with Slavic-speaking countries such as Bosnia, Serbia, Bulgaria, Wallachia and Hungary, which did not prevent it from facing financial difficulties in 1780. Thus, Dimitris Theodosiou was forced to collaborate with Pietro Marcuzzi, who also worked as a foreman at the printing house. At his death, on March 11, 1782, his son, Panos, takes over. Working diligently to turn the company around, in 1800 he succeeded in upgrading the publishing programs and enriching the printing equipment of the house. At the same time, he renewed the agreements with publishers in Slavic countries and hired Dositheos Obradovic as a proofreader, so that his Slavic publications would be more reliable. Probably as a result of new financial problems, Panos Theodosiou joined forces with the scholarly merchant Michael Vassiliou, but to no avail; the printing house soon ceased its activity for good. In the seventeenth and eighteenth centuries, during the period of Ottoman rule, and before Greece had its own printing press, Ioannina was an important center for the import and distribution of Greek-language books produced by local merchants who had established printing houses in Venice. Despite the persistent distrust of the Ottoman authorities of the time, expatriate booksellers such as Nikolaos Glykys and Nikolaos Sarros (late 17th century) and Dimitrios Theodosiou (mid-18th century) produced more than 1600 editions for distribution in Greece. The city's university now houses a printing museum.
