Bostanai

Bostanai (Hebrew: בוסתאני) was the first exilarch under Arabian rule; he flourished about the middle of the seventh century. The name is Aramaized from the Persian "bustan" or "bostan" (as proper name see Ferdinand Justi, Iranisches Namenbuch, p. 74). Almost the only exilarch of whom anything more than the name is known, he is frequently made the subject of legends.
