V. How do we know
| Claim | Evidence | Confidence | Sources |
|---|---|---|---|
| "After him Mar Rav Nachshon the gaon bar Mar Rav Tzadok the gaon, eight years" — placed c. 872–879 CE in the standard rosters.
The rosters' years overlap the end of Amram's tenure; the sources' figures for these decades disagree by a few years, and the overlap is left visible rather than harmonized.
|
tradition external | ★★★☆☆ | |
| No source names his teacher. Per this atlas's succession roster, Rav Sar Shalom bar Boaz and Rav Kohen Tzedek bar Ivumi held the headship of his academy during his formative window (c. 4595–4615 AM), making reception from them the likeliest reconstruction.
Derived by era-and-institution inference, not attested. The formative window is computed from this entry's schematic dates, hence the low confidence.
