A new documentary airing later this month on National Geographic Channel set out to investigate any possible truth behind the myth of the lost city of Atlantis, and while the people behind the program may or may not have solved the Atlantis mystery, they did come up with an important find.

Nat Geo announced that the team working on “Atlantis Rising,” which airs Sunday, Jan. 29, at 9 p.m. (8 p.m. CT), discovered a cache of ancient boat anchors that could rewrite the history of human travel in the Bronze Age.

The project includes Oscar-winning filmmaker James Cameron and three-time Emmy winner Simcha Jacobovici among its executive producers, with a group of archaeologists, scientists and historians on board.

“In the course of the expedition, the investigators discovered six ancient anchors that could date back to the Bronze Age and that together may be the greatest ancient anchor hoard ever found on the Atlantic side of the Strait of Gibraltar,” Nat Geo announced this week.

Said Jacobovici: “These anchors could be 3,500 to 4,000 years old and establish a harbor in the Atlantic, where I didn’t even dare dream to find anchors. It’s easier to find a needle in a haystack than Bronze Age anchors in the Atlantic.”

The network isn’t saying how the team did in its search for Atlantis itself, but notes: “The team used cutting-edge technology and Plato’s ancient writings as a virtual treasure map to lead the way. While many people search for a singular underwater site, ‘Atlantis Rising’ will embark on a journey from Greece to the Atlantic Ocean, exploring multiple locations on air, on land and deep below the sea with the goal to unlock the secrets of this age-old mystery.”

Professor and archaeologist Richard Freund of the University of Hartford, the team leader, commented: “This is the world’s most sophisticated and extensive search ever made.”
