Roman swords discovered in Dead Sea cave 1,900 years after Jewish rebellion

Further excavation of the same cave found artifacts dating as far back as the Chalcolithic period, about 6,000 years ago.

The unique dryness of the desert provides perfect conditions for the survival of ancient artifacts. Last year, experts announced the discovery of silver coins dating back 2,200 years, to the time of the Maccabean Revolt.
