Episode 1Garden of Eden min
The Garden of Eden, the Bible's most famous story, is considered by many to be an allegory about where humanity originated. But to some there is the possibility that this place exists on Earth. Now, the discovery of an archaeological wonder in southeast Turkey may hold the secret to the location of Adam and Eve's Paradise on Earth. Guided by host Adam Mastrelli, we investigate the oldest monumental structure ever built and see how it has revolutionized our understanding of prehistoric nomads.
Episode 2Jonah and the Whale min
On a mission to erase history, ISIS obliterated the shrine of the biblical prophet Jonah in Mosul, Iraq and may have inadvertently revealed the historical reality behind one of the Old Testament's most mysterious stories. Discover how an opportunity born out of the destruction of war helped archaeologists unearth new truths about the tale of Jonah and the Whale. Once dismissed as fiction, new evidence suggests that the prophet, the wicked king he warned to repent, and the original "Sin City" of Nineveh, may have been real.
Episode 3Shrunken Heads min
Thousands of shrunken heads are in museums around the world, some on display, and others locked away. Shockingly, many of them are real human heads. But what is the true story behind this strange and disturbing phenomenon? Host Adam Mastrelli reveals how a team of anthropologists, historians, and scientists are answering these questions by using modern forensic science and advanced computer modeling. Join us as we uncover the dark tale behind this ancient ritual.
Episode 4Ark of the Covenant min
The story of the Ark of the Covenant goes back many centuries. According to the Bible, it was built by the Israelites at God's command 3,000 years ago to hold stone tablets engraved with the original Ten Commandments, then vanished 500 years later from Jerusalem--and from history. Host Adam Mastrelli guides us through an international investigation, where teams sift through evidence and hunt for physical clues to prove if the ark was real and to determine if it still exists today.
Episode 5The Copper Scroll min
A team of archaeologists discovered a 2,000-year-old scroll in 1952 in a cave near the ruins of an ancient settlement, Qumran. It was classified as a Dead Sea Scroll, but with two distinct differences: it was made of copper and it did not contain biblical text. Instead, it gave clues to what may be the biggest hoard of treasure ever buried. A team of experts travels to the Holy Land to visit the cave where the metal scroll was discovered, investigate "ghost" inscriptions about the Colosseum, and determine if the riches were ever found.
