After some years as a monk at the abbey, probably with the encouragement of Saint Romuald (who later went on to found the Camaldolese branch of the Benedictines), Orseolo left the monastery to become a hermit in the surrounding forest, a calling he followed for seven years until he died.
Efter nogle år som munk i klosteret, formentlig med opmuntring fra Sankt Romuald (som senere grundlagde Camaldolese grenen af Benedictinerne), forlod Orseolo klosteret for at blive en eremit i de omkringliggende skove, et kald han fulgte i syv år indtil sin død.
