Thirteen crystal skulls of ancient origin have been discovered in parts of Mexico, Central America and South America, comprising one of the most fascinating subjects of 20th Century archaeology. These skulls, found near ancient ruins of Mayan and Aztec civilizations (with some evidence linking the skulls with past civilizations in Peru) are a mystery as profound as the Pyramids of Egypt, The Nazca Lines of Peru, or Stonehenge. Some of the skulls are believed to be between 5,000 and 36,000 years old. Many indigenous people speak of their remarkable magical and healing properties, but nobody really knows where they came from or what they were used for. Mr. Stephen Mehler will be joining us to help answer some of the many mysteries surrounding these remarkable artifacts.
