St. John of Egypt

One of the most famous early desert hermits, a noted prophet of his era. He was born in Lycopolis, modern Assiut, Egypt, and became a hermit at the age of twenty. He was walled up in a hermitage near Assiut, with a single window opening onto the public. There he preached to vast crowds each weekend. He predicted two military victories for Emperor Theodosius I, and they were proven accurate in 388 and 392. The cell in which John spent his life was discovered in 1925.
