Aaron Acharon (i.e. the younger), a rabbi born at Nicomedia in the beginning of the 14th century. He belonged to the sect of the Caraites. We have from him several Hebrew works on mystical theology (The Tree of Life, The Garden of Faith, The Garden of Eden), and a literal commentary on the Pentateuch, entitled סֵתֶר תּוֹרָה (vail of the law). — Hoefer, Biographie Generale, 1, 6.
