The Israel Antiquities Authority announced the discovery of four extremely well-preserved Roman swords hidden in a cave in the Judean Desert.

Dr. Asaf Gayer of the Department of the Land of Israel Studies and Archaeology at Ariel University noticed the swords in a remote cleft in the cave’s upper portion, as he and other researchers analyzed a Hebrew ink inscription, potentially from the First Temple Period, which was discovered 50 years ago.

Experts believe were captured by the Judean rebels during the Bar Kochba revolt and placed in a narrow crevice in the rock. Also called the Second Jewish Revolt, it was a Jewish rebellion against Roman rule in Judea led by rebel leader Simon Bar Kochba.

“We’re talking about an extremely rare find, the likes of which have never been found in Israel,” Dr. Eitan Klein, one of the directors of the Israel Antiquities Authority’s Judean Desert Survey, said in a video accompanying the announcement of the discovery. “Four swords amazingly preserved, including the fine condition of the metal, the handles, and the scabbards.”

Three of the swords are 60 to 65 centimeters long; one sword is 45 centimeters long. The longer swords are identified as Roman “Spatha” swords; the shorter one is a ring-pommel sword. Preliminary examination concluded that these were standard swords employed by Roman soldiers stationed in Judea.
