It added: “Back in the Forties, a pilot described seeing strange shapes as he flew over the area, but nobody seems to be interested.

“Goddio focuses on his strengths as a mathematician and statistician, spending days in front of his laptop, seeing the mystery as a calculable mathematical problem.

“Using an electromagnetic dragging technology, Goddio had the base, but it takes years of the research boat cutting back and forth according to a very precise plan.

“But his strict procedure does deliver results, entering all the details into his computer he puts together a complex visualisation of the seabed and there are some unusual features.

“He puts together an international team of scientists and divers, initially finding nothing, but finally, the divers make a discovery – large limestone blocks arranged next to each other.”

The series detailed how Mr Goddio began to piece together the possibility that he had found the ancient city, seeking expert opinion for help.

It added: “His methods seemed to work, the location of the walls seemed to correspond to the measurements already taken.

“Finally, Goddio is convinced that he’s discovered the legendary port, the city is clearly more than just a famed myth.

“He goes to get some academic back-up, approaching respected researchers at Oxford University’s Institute for Archaeology.

The series explained: “The international team of archaeologists set off on further expeditions to Egypt, dividing the seabed into a number of squares so they know exactly where they are in the murky water.

“Where they believe the Temple of Heracleion should be, they discover a large monolith, perfectly preserved, a shrine to Amun-Gereb.
