How do we know
| Claim | Evidence | Confidence | Sources |
|---|---|---|---|
| "And in these hundred years geonim stood at Mechasya: Mar Rav Hilai bar Mar Rav Mari, nine years" — placed c. 789–798 CE in the standard rosters.
The Iggeret gives tenure lengths without absolute anchors for Sura's geonim; CE anchoring follows the Sura Academy roster.

tradition external | ★★★☆☆ | |
| No source names his teacher. Per this atlas's succession roster, Rav Mari HaKohen, Yehudai Gaon, and Rav Ahunai Kahana held the headship of his academy during his formative window (c. 4505–4525 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.
