Seder Olam Rabbah סדר עולם רבה
The tradition's master chronology — the tannaitic work that counts the years from Creation and underlies the Anno Mundi dating used across this atlas. It is also where traditional and academic chronology part ways most sharply, in the length it assigns the Persian period.
I. Who
- Hebrew
- סדר עולם רבה
- Also known as
- Seder Olam
- Era
- tannaim
II. When
- Traditional
- taught by R' Yose ben Chalafta, mid-2nd c. CE (c. 3900–3930 AM)
- Academic
- tannaitic core; final chapters and redaction possibly amoraic or later
- Duration
- ≈30 years
- Precision
- approximate
IV. What
- Language
- Mishnaic Hebrew
- Redaction
- "Who taught Seder Olam? R' Yose" (R' Yochanan, in Yevamot 82b and Niddah 46b) — R' Yose ben Chalafta, of the generation of R' Meir (Rabbi Meir) and R' Shimon bar Yochai (Rabbi Shimon bar Yochai).
- Structure
- Thirty chapters of biblical-to-early-rabbinic chronology: chapters 1–10 from Creation to the entry into the Land, 11–27 to the destruction of the First Temple, 28–30 through the Second Temple period to the Bar Kokhba revolt.
V. How do we know
| Claim | Evidence | Confidence | Sources |
|---|---|---|---|
| R' Yochanan attributes the work to the tanna R' Yose (ben Chalafta): "Who taught Seder Olam? R' Yose." The attribution appears twice in the Bavli, both times introducing a citation from the work.
Verified in both passages; the Talmud elsewhere qualifies that R' Yose "taught it" without necessarily endorsing every position in it ("tani lah ve'lo savar lah", Niddah 46b).
|
rabbinic | ★★★★☆ | |
| Seder Olam's count assigns the Persian period (from the rebuilt Temple to Alexander) only 34 years, where academic chronology of the Achaemenid empire requires roughly two centuries — the ~166-year divergence the atlas marks as the chronology seam.
Both counts are stated on their own terms; the atlas positions entities by the traditional count and links the seam explainer.

tradition reconstruction | ★★★★☆ |
|
| Academic scholarship accepts a tannaitic core connected to R' Yose's school but treats the final redaction, especially the closing chapters, as later and text-critically unstable. | reconstruction | ★★★☆☆ |
