From Egyptology News:
An underwater robot will be used to search for the sarcophagus of ancient Egyptian Pharaoh Menkaure of more than 4,500 years ago off the Spanish coasts, the Egyptian MENA news agency reported on Saturday.
Egyptian and Spanish archeologists will launch the search in the historical city of Cartagena at the depths of the sea with the help of the hi-tech equipped robot, Egyptian Secretary General of Egyptian Supreme Council for Antiquities, Zahi Hawwas, was quoted by MENA as saying.
The merchant ship Beatrice carrying the sarcophagus of the ancient Egyptian king along with other antiquities sank off Cartagena in the early 19th century en route from Egypt to Britain, where some scientific studies were supposed to be conducted on them, Hawwas said.
Egypt and Spain will cooperate in a joint venture to locate the sarcophagus of Menkaure, the 5th king of the 4th Dynasty of Egypt who ruled from 2,551 BC to 2,523 BC.
