Seder Rav Amram Gaon סדר רב עמרם גאון

The first complete siddur — the order of all the year's prayers, sent as a responsum from Sura to Spain. Every siddur on every shelf descends from this act of the chain putting its own daily voice in writing; both the Sefardic and Ashkenazic rites cite it as their measuring rod.

IV. What

Language
Hebrew and Babylonian Aramaic
Redaction
A responsum of Rav Amram Gaon of Sura (Amram Gaon), answering a question from Spain with the complete order of the year's prayers and their halachot. The surviving manuscripts were working copies: later communities updated the prayer texts as they used them, so the halachic framework is better preserved than Amram's own liturgical wording (critical ed. Goldschmidt, 1971).
Structure
The year's liturgy in order — weekday, Shabbat, festivals, fasts, and life-cycle — each section giving the prayer texts inside a running frame of halachic instruction from the Talmud and the geonim.

V. How do we know

ClaimEvidenceConfidenceSources
The work presents itself as Rav Amram's answer to a request from Spain — "Amram bar Sheshna... to the scholars of Spain" — setting out the order of prayers and blessings for the whole year, the first complete such order transmitted in the chain. tradition ★★★★☆
The transmission is famously contaminated in the most honest way: because communities prayed from it, copyists silently adjusted its prayer texts to their own rite, so scholarship trusts the Seder's halachic skeleton while treating the liturgical flesh of the manuscripts as later — Goldschmidt's edition maps the divergence. reconstruction ★★★★☆
