 This was all done under the auspices of Serbian-born Metropolitan Anania of Wallachia at the time.After Dimitrije Ljubavić and his apprentices Opar and Petar completed printing "Apostol" in Targoviste in 1547, Dimitrije left for Constantinople, where he printed books for the Ecumenical Patriarchate of Constantinople for the next three years.From there he went to Mount Athos and printed more books at Hilandar and other island monasteries such as Docheiariou, Osiou Gregoriou monastery, Agiou Pavlou monastery, Dionysiou Monastery, Zograf monastery, and Koutloumousiou for more than two years.
