Israeli archaeologists on Tuesday unveiled a 2,000-year-old commemorative stone inscription dedicated to Roman Emperor Hadrian, which researchers say sheds light on the Jewish revolt against the ancient empire.

The stone, which measures a metre by a metre-and-a-half (three feet by five feet) and weighs a tonne, was found near the Damascus Gate entrance to Jerusalem’s Old City, with Israel’s Antiquity Authority (IAA) calling it “one of the most important Latin inscriptions” discovered in the Holy City.

The six lines in Latin, engraved in the hard white limestone, are a dedication from the Roman army honouring Emperor Hadrian, who visited the city in 130 AD and whose many building projects included the wall named after him in Britain to demarcate a border of the Roman empire.

The IAA said the stone may have originally been set into a gateway.

It was found on top of a deep cistern, with a semi-circle cut through the lower part of the inscription to allow access to the water.  “We have testimony in a new medium - stone - and a remnant of an original monument,” said Rina Avner, who led the IAA excavation along with Roie Greenwald. The event mentioned in the inscription took place before the so-called Bar Kokhba revolt (132-136 AD) against the Roman empire, she told AFP.
