Pillar-Saints, a class of recluses, called Stylites, who, in early Christian times, retired from the world to the Syrian Desert, and, perched on pillars, used to spend days and nights in fasting and praying, in the frantic belief that by mortification of their bodies they would ensure the salvation of their souls; their founder was Simon, surnamed Stylites; the practice, which was never allowed in the West, continued down to the 12th century.
