The patriarch of the Orthodox Church of Ethiopia says he will announce to the world Friday the unveiling of the Ark of the Covenant, perhaps the world's most prized archaeological and spiritual artifact, which he says has been hidden away in a church in his country for millennia, according to the Italian news agency Adnkronos.

Abuna Pauolos, in Italy for a meeting with Pope Benedict XVI this week, told the news agency, "Soon the world will be able to admire the Ark of the Covenant described in the Bible as the container of the tablets of the law that God delivered to Moses and the center of searches and studies for centuries."

The announcement is expected to be made at 2 p.m. Italian time from the Hotel Aldrovandi in Rome. Pauolos will reportedly be accompanied by Prince Aklile Berhan Makonnen Haile Sellassie and Duke Amedeo D'Acosta.
