"They want you to go for it!" Titanic discoverer Robert Ballard called to find lost sarcophagus

Built from polished blue basalt to transport the king's earthly remains to the next world, the elaborately decorated vessel lay hidden inside the third-largest of Giza's renowned Pyramids for more than 4,000 years. In 1837 the British colonel Richard William Howard Vyse blasted his way into Menkaure's sepulchral chamber using gunpowder and discovered the stone casket.

In a twist worthy of an Indiana Jones film, the sarcophagus was lost again the following year before it could reach British shores. The merchant ship Beatrice, which was carrying it and other antiquities found by the archaeologist, sank while sailing from Malta to Gibraltar — reportedly off the coast of Spain, near Alicante.
