Hammat Tiberias Synagogue בית הכנסת בחמת טבריה

Synagogue of the hot-springs town Hammta, adjacent to Tveria (Tiberias), with the finest 4th-century CE mosaic floor found in the land of Israel: a Torah shrine flanked by menorahs, a zodiac wheel with Helios in his chariot at the center, and Greek dedications naming donors — chief among them Severos, "threptos of the illustrious patriarchs," a rare epigraphic voice of the Nesi'ut, the patriarchal house seated in Tiberias.

V. How do we know

ClaimEvidenceConfidenceSources
The site was first excavated by Nahman Slouschz in 1921 — the first excavation conducted by a Jewish archaeological society in the land of Israel — and systematically by Moshe Dothan (1961–1963), whose stratum IIa synagogue with the Severos mosaic is dated to the fourth century CE on stratigraphic and stylistic grounds. archaeology ★★★★★
Among the mosaic's Greek dedications, Severos is titled "threptos of the illustrious patriarchs" — one of the very few inscriptions anywhere naming the household of the Jewish patriarchate, the institution the Talmud calls the Nesi'ut, then seated in Tiberias; the floor thus places this synagogue in the orbit of the rabbinic leadership of amoraic Galilee. archaeology external ★★★★☆
The floor's central panel is a zodiac wheel with the sun god Helios driving his chariot, the twelve signs labelled in Hebrew, and the four seasons in the corners — the earliest and finest of the synagogue zodiacs, and the central puzzle of late antique Jewish art: an apparently pagan sun figure at the heart of a house of prayer, variously explained as calendar diagram, emptied decorative convention, or symbol of divine power.
The mosaic itself is undisputed; the confidence grade reflects the unresolved interpretation of Helios in synagogue floors.

The town is the biblical Chamat of Naftali's fortified cities, which the gemara identifies with the hot springs by Tveria: "Chamat — this is Tiberias; and why was it called Chamat? Because of the hot springs of Tiberias." Ancient Hammta lay immediately south of Tveria and merged with it in the rabbinic period. biblical rabbinic ★★★★☆
