An early medieval Middle Persian Zoroastrian source known as The Provincial Capitals of Ērānšahr describes the provinces and major cities of the Sasanian Empire and supplies several of them with short foundation myths. In describing the establishment of the cities of Susa and Šuštar in Khuzistan, The Provincial Capitals reports that they “were built by Šīšīnduxt, the wife of Yazdgird, the son of Šābuhr, since she was the daughter of the Exilarch (rēš-galūdag), the king of the Jews (jahūdagān šāh), and was also the mother of Wahrām Gōr.”
