JERUSALEM — Vandals badly damaged a rare 1,600-year-old mosaic in the northern Israeli city of Tiberias that formed the floor of an ancient synagogue, smashing parts to rubble and scrawling graffiti, antiquity officials said Tuesday.
Experts suspect extremist Jews who object, sometimes violently, to excavations they claim involve ancient grave sites. There was no claim of responsibility. Police are investigating.
Guards found the damage on Tuesday morning, said archeologists involved in the site.
The mosaic, dating 400 years after the birth of Jesus, was one of the best preserved and beautiful of its period, according to archaeologists.
It featured illustrated zodiac signs and the traditional symbolism of a fourth-century synagogue: ritual candelabras and palm fronds. The synagogue's ruins, including its ancient mosaic floor, were in a fenced-off area of a national park in Tiberias, next to the Sea of Galilee.
It listed the names of the synagogue's chief patrons in ancient Hebrew, Latin and Greek.
Israel Antiquities Authority deputy director Uzi Dahari said a fringe group of ultra-Orthodox Jews were suspected of causing the damage, much of it irreversible. Dahari said the graffiti scrawled across parts of the archaeological site and previous threats against the Antiquities Authority suggested they were the perpetrators.
Photographs issued by the Antiquities Authority showed parts of the mosaic floor reduced to gray chunks of rubble. Other photographs showed blue spray paint scrawled over the mosaic, covering ancient Hebrew and Greek letters spelled out in blue, red and beige tiles. Graffiti was also scrawled along rock walls beside the mosaic. Perpetrators also punched a hole in the mosaic between two candelabras.
