Tomorrow is the commemoration of the Seven Sleepers of Ephesus, one of the odder tales in Orthodox hagiography. Recountings of it can be found at this page from St. John's Cathedral of the Russian Church Abroad and on this page from the OCA website. The story of the Seven Sleepers was popular in both Eastern and Western Christendom and a version of it can be found in the Koran. For the skeptic, it is an interesting folktale. For the believer, it is a story of faithfulness in persecution, and a living parable of the Resurrection.
The cave where the Seven slept was later turned into a pilgrimage site. The ruins of the site remain today and pictures of it can be found here.
