tradition | ★★★★☆ | |
| No source names his teacher. Per this atlas's succession roster, Rav Abba bar Dodai and Rav Chananya bar Mesharshiya held the headship of his academy during his formative window (c. 4521–4541 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.
