King Midas
Most of us have heard of King Midas who was cursed with the ability to turn anything he touched into gold, giving us the expression the Midas touch. While he most likely existed as a real king, it is highly unlikely that the story he is known for is historically accurate. It is, however, a great part of Greek mythology.
Jack the Ripper
Jack the Ripper was an unidentified serial killer who was active in impoverished areas of London in 1888. He has never been identified, so it’s really hard to know whether all the murders attributed to him were actually committed by the same, one person. The murders remain unsolved to this day, leading many Jack the Ripper legends becoming a combination of pseudo-history, folklore, and historical research.
