David Childress, popular author and star of the History Channel's show Ancient Aliens, takes us on an incredible journey in search of the truth about (and science behind) the fantastic Biblical artifact known as the Ark of the Covenant. This object made by Moses at Mount Sinai–part wooden-metal box and part golden statue–had the power to create "lightning" to kill people, and also to fly and lead people through the wilderness. Featured in such popular movies as Raiders of the Lost Ark by Lucas and Spielberg, the Ark of the Covenant is probably the most mysterious object in the Old Testament–what was it? The Ark of the Covenant suddenly disappears from the Bible record and what happened to it is not mentioned. Was it hidden in the underground passages of King Solomon's temple and later discovered by the Knights Templar? Was it taken through Egypt to Ethiopia as many Coptic Christians believe? Childress looks into hidden history, astonishing ancient technology, and a 3,000-year-old mystery that continues to fascinate millions of people today.
