“He (Macarius of Egypt) made in the course of time a tunnel running under the ground from his cell for half a stade and finished it off at the end with a cave. And if ever a crowd of people troubled him, he would leave his cell secretly and go away to the cave and no one would find him. Now one of his zealous disciples told us this, and said that he used to pray twenty-four prayers on his way to the cave and twenty-four as he returned.” – The Lausiac History
