“The most misguided ‘saints’ of those times were the Stylites or Pillar Saints. They took their name from a certain Simeon who died in 459 at the age of about 70. ‘Stylos’ is the Greek word for a pillar. Simeon imagines that by living on the top of a pillar his soul would benefit. Beginning with a pillar about six feet high, and gradually increasing its height, he ended up living for over 30 years on a pillar 60 feet high. He had many visitors and he preached to them from the top of his pillar. Some of the visitors erected pillars of their own, normally in the region of Antioch of Syria” (Sketches, 28).
