Early Life and Monastic Formation
By tradition he was born in 1714 in Majdan (in the area of Mrkonjić Grad), Bosnia, and given the baptismal name Nicholas (Serbian sources record his parents as Maksim and Marija). Around the age of eighteen he traveled to the Holy Land, where he took monastic vows at the Monastery of Saint Sava the Sanctified near Jerusalem; sources place his tonsure in 1738, by which he received the monastic name Bessarion (Visarion).
He served for about seven years as a hierodeacon at the Monastery of Pakra in Slavonia, where he was later ordained a hieromonk, and is also said to have visited the monasteries of Mount Athos. For a time he withdrew to live as a hermit in a cave.
