"And in his days [Mar Rav Mari's], Mar Rav Mar ben Mar Rav Huna the gaon was in Sura, in the year 920" (Sel. 920 = 4369 AM = 609 CE). Only the single anchor year is given, so the role carries its start alone.	tradition	★★★★☆	Iggeret Rav Sherira Gaon 1:112
The standard rosters place Mar ben R. Huna at 591 CE — two decades before the Iggeret's anchor (Sel. 920 = 609 CE). The Iggeret's own year is followed for the role; the chronicle variant is preserved here rather than harmonized. Chronicle-grade (not Iggeret-attested): from the conventional geonic lists; where the two grades conflict, the Iggeret wins and the variant stands recorded.	external reconstruction	★★☆☆☆	Sura Academy (roster of deans)
