"The excavation revealed a huge religious center with three sanctuaries, a sacred lake, more than 1,500 objects, busts, statues, golden pieces, a huge collection of coins portraying Alexander the Great, Queen Cleopatra and the Ptolemies," Martinez told CNN."She was an educated woman, probably the first one who studied formally at the Museum in Alexandria, the center of culture in her time," according to Martinez, who said she admires Cleopatra as a student, a linguist, a mother and a philosopher.A series of clues led Martinez to believe Cleopatra's tomb might be located in the Temple of Osiris in the ruined city of Taposiris Magna, on Egypt's northern coast, where the Nile River meets the Mediterranean.The excavations so far have revealed that "the temple was dedicated to Isis" -- which Martinez believes is another sign that the lost tomb lies nearby -- as well as the tunnels below the sea.According to a statement issued by the Ministry of Tourism and Antiquities, the Egyptian coastline has been battered by earthquakes over the centuries, causing parts of the Taposiris Magna to collapse and sink under the waves."
