Delos Synagogue (GD 80) בית הכנסת בדלוס וכתובות השומרונים

A building on the eastern shore of the sacred island of Delos — known by its excavation number GD 80 — with benches lining the walls, a marble seat of honor, and dedications to "Theos Hypsistos" (the Most High God). Excavated by André Plassart in 1912–13, it is widely identified as a synagogue of the second to first centuries BCE, which would make it the earliest synagogue building identified anywhere; the identification itself is honestly debated. Separately and securely, two marble inscriptions found nearby in 1979–80 record "the Israelites on Delos who send offerings to holy Argarizein" (Har Gerizim) — the earliest evidence anywhere for an organized Samaritan diaspora community, worshipping alongside, and distinctly from, the island's Jews.

ClaimEvidenceConfidenceSources
Building GD 80, in the residential quarter near the stadium on the island's eastern shore, was excavated by André Plassart in 1912–13: a hall subdivided in a later phase, with marble benches along the walls, a carved marble seat ("throne"), a cistern, and small dedications on columns and plaques to Theos Hypsistos — "the Most High God" — with formulae paralleled in Jewish usage. Its period of use falls in the second and first centuries BCE, Delos's boom era as a free port. archaeology ★★★★★

  • Delos Synagogue
The identification of GD 80 as a synagogue is debated, and the atlas says so plainly. Plassart and, after re-examination, Bruneau and L. Michael White read the benches, the Hypsistos dedications, and the building's plan as a Jewish (or Samaritan) prayer hall — on that reading, the earliest synagogue building known anywhere. Skeptics note that no unambiguous Jewish symbol or explicitly Jewish inscription was found in the building itself, and that a pagan cult association of Theos Hypsistos could produce the same remains. Most current scholarship accepts the synagogue identification as probable but not proven.
If the identification holds, GD 80 predates every synagogue building in the Land of Israel yet excavated; that is precisely why the atlas keeps the caveat attached.
archaeology ★★★☆☆
Two marble inscriptions found in 1979–80 by Philippe Bruneau, about 90 meters north of GD 80, are secure and remarkable: each is a dedication by "the Israelites on Delos who send offerings to holy Argarizein" — Har Gerizim — honoring benefactors of the community. Dated by letter forms between the third/second and early first centuries BCE, they are the earliest evidence anywhere for an organized Samaritan diaspora community, defining itself by loyalty to Gerizim rather than Yerushalayim. The stones are held in the Archaeological Museum of Delos. Whether GD 80 served this Samaritan group, a Jewish congregation, or neither is a separate and open question — the atlas keeps the two threads apart. archaeology external ★★★★☆
Tanakh traces the Samaritans (Kutim) to populations settled in the cities of Shomron after the Assyrian exile, who "feared Hashem and served their own gods"; their sanctuary on Har Gerizim and the enduring split with Yerushalayim run through the books of Ezra and Nechemya into the Second Temple period. The Delos stones show that split carried across the sea: a diaspora community on a small Greek island still sent its offerings to Gerizim, not Yerushalayim, generations before the churban. biblical external ★★★★☆
