Aaron ben Isaac Sason was an Ottoman author and Talmudist; born in Constantinople in 1629.
He was a grandson of Aaron ben Joseph Sason, an eminent Talmudist, and cousin of Ḥayyim Benveniste, the famous scholar.
Aaron Cupino, rabbi of Constantinople, was his teacher in Talmudic lore, and was so successful that at the age of twenty his pupil engaged in Talmudic controversies with Moses Benveniste, who thought them worthy of publication.
A Palestinian commentator Judah Rozanes referred with respect to an unpublished work, "Hen Yeshallaḥ," by R. Aaron.
Shabbethai Bass, the only writer who mentions that particular book, in his "Sifte Yeshenim," throws no light on this question, merely mentioning that it is by Aaron Sason.
