In the summer of 1988 Robert Ballard and his team discovered the remains of an ancient Roman ship in the deep Mediterranean. In 1989 they returned to explore the shipwreck site with a high-tech underwater robot called Jason, which was equipped with lights and cameras. This book tells of the discovery of the ship, puts it in its historical context in the 4th century AD and describes it's rediscovery in 1989 and the explorations of the wreck that ensued. Anna Marguerite McCann is the archaeological and historical consultant on the book.
