Blackbeard, the world's most famous pirate, lost his flagship in 1718 when the ship ran aground on a sandbar in North Carolina. But in 1996, the wreck of the Queen Anne's Revenge was rediscovered, and archaeologists began excaviting the ship.

Since then, the excavation project has revealed that the ship contained many medical instruments of the day, hinting that Blackbeard put great effort into keeping his crew healthy. [Full story: Blackbeard's Booty: Pirate Ship Yields Medical Supplies]
