Beit Alfa Mosaic: One-day preservation effort completes

Conservation specialists from the Israel Nature and Parks Authority finished a major maintenance operation on the ancient synagogue floor at Beit Alfa National Park in northern Israel earlier this week. The team of about 20 experts, directed by the authority’s Archaeology and Heritage Division, completed work in one day that typically requires several days to finish.

The staff cleaned the surface, secured loose stones, and strengthened weak areas. They filled gaps between the tiles with binding materials that match the original composition, a process known as repointing. The authority documented the floor’s condition before and after the intervention to aid future monitoring and maintenance planning.

The synagogue dates to the late fifth century CE during the Byzantine period. Its structure includes a courtyard, a corridor, a rectangular central hall, an upstairs balcony, and an additional room. An Aramaic inscription in the floor, which is missing much of its right side, dates the mosaic to the reign of Emperor Justinian I, who ruled from 527 to 565.

A separate Greek inscription identifies the creators as Marianus and his son Hanina. Their names also appear at the Beit She'an synagogue, indicating their workshop was likely based there. The artwork at Beit Alfa consists of three colorful panels depicting the Ark of the Covenant, the zodiac, and the Binding of Isaac.

The zodiac panel shows 12 Hebrew-labeled signs surrounding Helios, the Greek sun god, who drives a chariot across the sky. A female figure at each corner of the square border represents the four seasons. The Binding of Isaac panel shows Abraham holding a knife above his son, with a hand appearing overhead to signal God’s command. The top panel displays the Ark beneath a shell motif, flanked by seven-branched menorahs and other religious items including a shofar, fire pan, etrog, and lulav.

Professor Eleazar Lipa Sukenik of Hebrew University of Jerusalem discovered the mosaic in 1928. Sukenik helped the Israeli government purchase the Dead Sea Scrolls. His son, Yigael Yadin, later served as the IDF’s second chief of staff and became a prominent archaeologist. Orit Bortnik, director of the Archaeology and Heritage Division, noted the floor contains more than 800,000 small stones assembled roughly 1,500 years ago. She described the preservation as a responsibility to keep the record of the artists and residents intact.

The team’s combined effort allowed them to finish the complex restoration within the single day window. The authority will use the recorded data to guide future care of the site.
