The Cairo Genizah is well known as a repository for hundreds of thousands of manuscripts that the Jewish residents of Fustat (Old Cairo) produced and consumed in the premodern period. Foreign “collectors” acquired most of these manuscripts for European libraries in the second half of the nineteenth century, with the majority arriving at the Cambridge University Library in 1897 under the auspices of Solomon Schechter. Less well known is the fact that hundreds of Genizah fragments were produced in the late nineteenth century, even as European collectors were scouring Cairo for ancient texts. This later corpus includes witnesses to the social and economic history of late Ottoman Cairo and provides copious evidence for the material history of Egyptian Jewish literary activity at that time. Despite this, it remains understudied for both Ottoman and Jewish history. Late Genizah material also raises questions about the integrity of “Cairo Genizah” manuscript collections around the world, as some fragments postdate Schechter's Genizah “discovery,” and others were never in Egypt at all.

Halper 331 is the fragment of a codex that has been styled the ‘oldest dated document of the Cairo Genizah’. It preserves the opening of a Jewish legal document dated to the year 1182 (Seleucid era), which appears to have been copied into this codex, probably as a formulary, not long after this date, in the late 9th century. In this article, the text of this fragment, in Aramaic and Hebrew, is edited, and its identification as the beginning of a marriage contract (ketubbah) is evaluated. Its Egyptian provenance is questioned, partly because the earliest evidence for the introduction of the Seleucid era by Jews in Egypt dates from the mid-10th century. The article surveys the history of Jewish dating methods in early medieval Egypt and the Near East, in an attempt to clarify this question. The specific date of the document deviates from the rabbinic calendar, but agrees with that of the contemporary Jewish Near Eastern sectarian groups of Abū ʿImrān al-Tiflīsī and Ismāʿīl al-ʿUkbarī; this document could thus uniquely attest one of these sectarian Jewish calendars.

This is a first-time presentation of the initial section of the Toledot Yeshu (TY) narrative describing the birth and early life of Jesus in Judeo-Arabic, a text with important implications for current research on TY. First, the origin of the birth narrative has been debated in recent scholarship on the Hebrew versions of TY. The existence of this lengthy Judeo-Arabic birth narrative, preserved in two manuscripts belonging to the Russian National Library, as well as the identification of other, earlier Judeo-Arabic manuscript fragments that include the TY birth narrative, demonstrates that the birth narrative formed part of TY significantly earlier than has been previously suggested. Second, the narrative preserved in the Russian manuscripts also demonstrates the relevance of the Judeo-Arabic versions of TY for the understanding of the development of this protean work. Examination of their textual tradition reveals interesting connections with particular Hebrew versions of TY from Europe and can shed light on the question of how the work moved between East and West. Finally, this Judeo-Arabic version of TY is significant in its demonstration of a clever adaptation to its linguistic and cultural surroundings. It incorporates a lengthy introduction—the only one currently known in all of the TY literature—which is a literary tour de force employing contemporaneous Arabic style together with a well-known rabbinic dictum, thereby situating Toledot Yeshu simultaneously in its Islamicate milieu and in Jewish textual and even ritual tradition. The discussion concludes with a transcription and translation of the birth narrative as preserved in these two Russian manuscripts.

This article presents a plethora of fragments from the medical notebooks found in the Cairo Genizah that comprise a unique source of historical data for scholarly study and for a better understanding of the ways in which medieval medical knowledge in Egypt was transferred from theory to practice and vice versa. These documents provide the most direct evidence we have for preferred practical medical recipes because they record the choices of medical practitioners in medieval Cairo. Since the language most commonly used in them was Judaeo-Arabic, they were evidently written by Jews. The medical genre in the notebooks was primarily pharmacopoeic, consisting of apparently original recipes for the treatment of various diseases. There are also a few notebooks on materia medica. The subject matter of the Genizah medical notebooks shows that they were mostly of an eclectic nature, i.e. the writers had probably learnt about these treatments and recipes from their teachers, applied them at the hospitals where they worked or copied them from the books they read. Foremost among the subjects dealt with were eye diseases, followed by skin diseases, coughs and colds, dentistry and oral hygiene, and gynaecological conditions. The writers of the Genizah notebooks apparently recorded the practical medical knowledge they wished to preserve for their future use as amateur physicians, students, traditional healers or professional practitioners.
