[1] His maternal grandfather was Solomon Oheb, also a rabbi in the same city.
Aaron studied in his native city and later in Venice, whence he returned to occupy a pulpit in Ragusa.
In 1623 he was imprisoned as a supposed accomplice of Isaac Jeshurun, who had been falsely accused of ritual murder.
Rabbi Aaron's sermons, Zeḳan Aharon (Aaron's Beard), together with his grandfather's sermons, Shemen ha-Ṭob (The Good Oil), and the history of Isaac Jeshurun's martyrdom, were published at Venice in 1657,[2] after his death.
[1] Aaron's account of the alleged ritual murder, together with documents from the Ragusa archives, were published in 1882.
