Over a hundred years ago, some divers jumped into the Mediterranean to look for sponges. Instead, they found ancient treasures. Artefacts, statues, jewellery. And a corroded piece of bronze. Little did they know that lump of metal would be the most valuable of the lot.  Ancient Greek cultural historian Dr Tatiana Bur from the Australian National University tells Marc Fennell (Stuff The British Stole) the story of the Antikythera mechanism. From how it was salvaged from the ocean floor, to being called the world’s first computer and how it’s transformed our understanding of ancient civilisations and technology.    Binge all the episodes of No One Saw It Coming now on the ABC listen app (Australia) or wherever you get your podcasts.   Get in touch: Got a story for us?
