After a disagreement with Radu, Nifon left Wallachia as an old man, and returned to the Dionysios Monastery, where he lived in anonymity, concealing his identity. Indeed, the duties given to him were insignificant, routine ones, such as the care of the animals and the observation of the sea to give advance warning of any potential incursion by pirates, at the same spot where a chapel was later built in his honour. At one point, however, his true identity was miraculously revealed to the monks. He resided in the Monastery until his death on August 11, 1508, at the age of 90. His tomb is in the cemetery of the Monastery, outside the chapel of All Saints.
