“Epimenides was sent by his father into the field to look for a sheep, turned out of the road at mid-day and lay down in a certain cave and fell asleep, and slept there fifty-seven years; and after that, when awake, he went on looking for the sheep, thinking that he had been taking a short nap.”
Epimenides, 2.
