What can we learn from the recent return to the Greek waters of Antikythera, the shipwreck site where the famous Antikythera mechanism was recovered?
What do we now know about this 2,000-year-old proto-computer, and what other ancient Greek technologies might remain to be discovered?
The Antikythera wreck was discovered in 1900, and subsequently explored by Jacques Cousteau in 1976.
The boat is thought to be Roman, dating back to the first century BC.
The marine archaeologist Brendan Foley has been exploring the site with Greek archaeologists since 2012, using new diving technology which allows for a fuller, complete survey of the Antikythera Wreck site. He's assembled a team of the world's top technical divers, along with new equipment such as state of the art robotic submarines, and the Exosuit, the world's most advanced diving suit.
Brendan Foley joins Ian Sample down the line, along with Dr Serafina Cuomo, who works at Birkbeck, University of London on the history of mathematics and technology in ancient Greek and Roman times, and by the journalist Jo Marchant, author of Decoding the Heavens: Solving the Mystery of the World's First Computer.
Jo wrote about the latest expedition to the Antikythera wreck in February's Smithsonian Magazine.
