John the Silent, bishop and saint
Saint John the Silent (c. January 8, 454 – c. 558), also known as St John the Hesychast (Greek: Ἅγιος Ἰωάννης ὁ Ἡσυχαστής), was a Christian saint known for living alone for seventy-six years. He was given the surname because of his affinity for recollection and silence. St. John's feast day is May 13 in the Latin Rite of the Roman Catholic Church, and December 3 in the Eastern Orthodox and Eastern Catholic Churches.
