The Rise and Fall of Atusi

Atusi was raised as a Twelver Shiite, but he may have had leanings towards Ismaelism early in life. He fled to the shelter of the Nizari rulers, whose conflicts with other Muslims gave them good reason to build nearly impregnable fortresses. By the time he is writing his works under the sheltering wing of the Nzadis, Atusi is already a formidable scholar and polymath.
