Venerable Niketas, John and Joseph, hermits of Chios and founders of the Nea Moni.
Niketas, John and Joseph were hermits on Mount Provateion in Chios in the eleventh century. Tradition relates that they found an icon of the Theotokos hanging in a myrtle tree and, foretelling the rise of Constantine Monomachos to the throne, received from him the means to build the Nea Moni.
The monastery became one of the glories of Byzantine art, and the three founders are honored on May 20.
