The 20 Coolest Unsolved Mysteries in History

The Uffington White Horse

Nearby Stonehenge lies another elegant puzzle tossed to us by our Bronze Age ancestors. The Uffington White Horse is a massive, stylized drawing etched into the chalky fields of Oxfordshire. It's almost 400-feet-long and about 3000-years-old, and the best view of it is from the sky (unlike other chalk drawings in England, which non-flying peeps can see). There are dozens of theories about its origins, purpose, and even what it's supposed to be — a horse? A dragon? A horse-dragon? It's a total mystery, though it's been assumed to be a horse for over 1,000 years now. Terry Pratchett has further enhanced the drawing's fame by having one of his characters say that it isn't "what a horse looks like, it's what a horse be" about the figure's mesmerizing elegance.
