Prague's Legend of the Silver Fish

A legend says that a wealthy man called Myslík was forced to run away from Prague after the battle of the White Mountain. He gathered all his precious silver and melted it in a fish-shaped clay mould. Before leaving his beloved Prague, Myslík hid the silver fish inside a wall of his house. Many years later a new tenant was living in that house. One day, this man was ordered by the city counselors to tear down the old building and build a new one. The poor man fell into despair at the news as he didn't have the money to do that. He was about to leave his house when Myslík's silver fish fell out of a broken wall. The precious object allowed the man to restore his old house. This legend is still well known in Prague and the moral of this story is that someone's misfortune may always turn into someone else's good luck and so we should never lose our hope.
