The Great Basses wreck is an early 18th-century shipwreck on Great Basses Reef, about 12 km off the south coast of Sri Lanka, discovered by Arthur C. Clarke and Mike Wilson in 1961. The ship, ultimately identified as belonging to the Mughal Emperor, Aurangzeb, yielded fused bags of silver rupees, cannons, and other artifacts, carefully documented, became the basis for the book "The Treasure of the Great Reef".[2] [3]
