true story

A large looking-glass is fixed above a well, which is not very deep. If a man goes down into the well, he hears everything that is said among us on earth, and if he looks into the looking-glass he sees every city and every country just as if he were standing over it. When I tried it I saw my family and my whole native land, but I cannot go further and say for certain whether they also saw me.
