This historical study argues that the Mandaean religion originated under Sasanid rule in the fifth century, not earlier as has been widely accepted. It analyzes primary sources in Syriac, Mandaic, and Arabic to clarify the early history of Mandaeism. This religion, along with several other, shorter-lived new faiths, such as Kentaeism, began in a period of state-sponsored persecution of Babylonian paganism. The Mandaeans would survive to become one of many groups known as Ṣābians by their Muslim neighbors. Rather than seeking to elucidate the history of Mandaeism in terms of other religions to which it can be related, this study approaches the religion through the history of its social contexts.

The Talmud's Red Fence explores how rituals and beliefs concerning menstruation in the Babylonian Talmud and neighboring Sasanian religious texts were animated by difference and differentiation. It argues that the practice and development of menstrual rituals in Babylonian Judaism was a product of the religious terrain of the Sasanian Empire, where groups like Syriac Christians, Mandaeans, Zoroastrians, and Jews defined themselves in part based on how they approached menstrual impurity. It demonstrates that menstruation was highly charged in Babylonian Judaism and Sasanian Zoroastrian, where menstrual discharge was conceived of as highly productive female seed yet at the same time as stemming from either primordial sin (Eve eating from the tree) or evil (Ahrimen's kiss). It argues that competition between rabbis and Zoroastrians concerning menstrual purity put pressure on the Talmudic system, for instance in the unusual development of an expert diagnostic system of discharges. It shows how Babylonian rabbis seriously considered removing women from the home during the menstrual period, as Mandaeans and Zoroastrians did, yet in the end deemed this possibility too "heretical." Finally, it examines three cases of Babylonian Jewish women initiating menstrual practices that carved out autonomous female space. One of these, the extension of menstrual impurity beyond the biblically mandated seven days, is paralleled in both Zoroastrian Middle Persian and Mandaic texts. Ultimately, Talmudic menstrual purity is shown to be driven by difference in its binary structure of pure and impure; in gendered terms; on a social axis between Jews and Sasanian non-Jewish communities; and textually in the way the Palestinian and Babylonian Talmuds took shape in late antiquity.

Late Antique Responses to the Arab Conquests is a showcase of new discoveries in an exciting and rapidly developing field: the study of the transition from Late Antiquity to Early Islam. The Arab conquests are shown to have changed both the Arabian conquerors and the conquered.

This collection of articles analyzes the formation of antique and early medieval religious identities and ideas in rabbinic Judaism, early Christianity, Islam, and Greco-Roman culture. The authors question the artificial disciplinary and conceptual boundaries between these traditions.

The Haran Gawaita (Mandaic "Inner Haran" or "Inner Hauran") is a Mandaean text which purports to tell the history of the Mandaeans and their arrival in Media as "Nasoraeans" from Jerusalem
