So far, authorities have not had a close enough look to know who is in the tomb. Workers have been clearing rubble to allow archeologists to examine it.
Egypt's antiquities authority has said only that the single-chamber tomb contains five wooden sarcophagi, in human shapes with colored funerary masks, surrounded by 20 jars with their pharaonic seals intact -- and that the sarcophagi contain mummies, probably from the 18th Dynasty, about 3,300 to 3,500 years ago.
Further details were expected today when antiquities chief Zahi Hawass was to unveil the tomb.
Officials were tightlipped yesterday, a day after announcing the find. Calls to Hawass and other officials were not answered. American archeologist Otto Schaden, who headed the team that uncovered the site, declined to answer any questions when contacted by the Associated Press.
Photos released by the Supreme Council of Antiquities showed the interior of the tomb -- the bare stone walls undecorated -- with at least five sarcophagi of blackened wood amid white jars, some apparently broken. What appeared to be a sixth sarcophagus was set on top of two of the other coffins, though the council's statement mentioned only five.
The tomb may provide less drama than the famed opening of King Tutankhamun's tomb in 1922 by British archeologist Howard Carter, a discovery that revealed a treasure trove of gold artifacts along with the boy-king's mummy.
But it raises hopes that more is to be found in the Valley of the Kings, which, for 83 years, specialists believed held only the 62 previously known tombs, labeled KV1-62 by archeologists.
''I wouldn't be surprised if we discover more tombs in the next 10 years. For a long time, people thought there was nothing left to find and excavations seemed unlikely to produce much. So instead, they concentrated on recording what was already there," Weeks said.
Weeks made the last major discovery in the valley. In 1995, he opened a previously known tomb -- KV5 -- and found it was far larger than expected: more than 120 chambers, which he determined were meant for sons of the pharaoh Ramses II.
