| "And after him, in the year 201 [Sel. 1201 = 890 CE], Mar Rav Hai bar Rav Mar David, seven and a half years."

tradition | ★★★★☆ | |
| No source names his teacher. Per this atlas's succession roster, Rav Matityahu held the headship of his academy during his formative window (c. 4615–4635 AM), making reception from him 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.
