Daniel Chwolsohn

← Encyclopedia

Daniel Chwolsohn (1819–1911) was a Russian orientalist whose two-volume Die Ssabier und der Ssabismus (1856) gathered, for the first time, the Arabic and Syriac sources on the Sabians — among them the pagans of Ḥarrān who claimed Hermes as their prophet — and remained the working sourcebook for that subject for more than a century.

He was born into a poor Jewish family in Vilna and educated first in the Talmud, then in the Semitic philology of the German universities — Breslau, where he heard the Arabist Heinrich Fleischer’s pupils, and Leipzig, where Fleischer himself presided over the discipline that was then making Arabic, Syriac, and the older Aramaic dialects into instruments of exact scholarship rather than missionary apologetics. The trajectory was the one open to a gifted yeshiva-trained mind in the 1840s: from the closed world of rabbinic study, with its mastery of an Aramaic that the Talmud itself is half written in, out into the comparative grammar of the Semitic languages, where that mastery became professional capital. The transition cost something and gained something, and the cost and the gain ran together for the rest of his life.

In 1855 he converted to Russian Orthodoxy and took the chair of Hebrew, Syriac, and Chaldaic in the newly opened Oriental faculty at St. Petersburg — a professorship a practicing Jew could not then hold. (“Chaldaic” here is the nineteenth-century name for the Aramaic of the Targums and the Talmud and the Syriac of the Christian East, the philological territory of his training; it has nothing to do with the late-antique Chaldean Oracles.) A much-repeated anecdote, perhaps polished in the telling, has him asked whether he had converted out of conviction, and answering that he had: the conviction that it was better to be a professor in St. Petersburg than a schoolmaster in a shtetl. The line is too good to take as testimony; it survives because it captures, in one stroke, the bargain that a confessional state forced on its most learned subjects, and the dry exactness of the man who took it. Whatever the inner accounting, he spent much of his later career defending the community he had formally left. When a blood libel — the medieval accusation that Jews murder Christians for the ritual use of their blood — was raised against the Jews of Saratov in the late 1850s, Chwolsohn was appointed to a government commission of scholars and wrote the report that demonstrated the charge’s groundlessness; the memoir grew, across a republication at St. Petersburg in 1880 occasioned by a fresh accusation at Kutais in Transcaucasia in 1878, into the full-scale study that appeared in German in 1901 as Die Blutanklage und sonstige mittelalterliche Beschuldigungen der Juden — the blood accusation and other medieval charges against the Jews. Against a libel that no quantity of evidence ever quite killed, he marshaled the same philological control he brought to the Sabians: the rabbinic and historical record, read closely, turned against the slander built on its margins. The professor of a foreign church remained, in this, an advocate for the people he was born to — and the breadth of his learning carried into work of a different temper, including the survey of the Semitic peoples that reached English readers in 1874 as The Semitic Nations.

The Sabian question

The Sabian book addressed a real puzzle, and the puzzle is older than any modern scholarship. The Qurʾān extends protection to a people called the Ṣābiʾūn — named three times, beside Jews and Christians, among the communities owed toleration — without saying who they are. Into that silence medieval Muslim jurists and heresiographers poured a long argument about which living group, if any, could lawfully claim the name and the protection it carried. Arabic writers attached the label above all to the star-worshippers of Ḥarrān, the old Mesopotamian city — classical Carrhae — that had kept the temples of the moon-god standing into the Islamic centuries and that treated Hermes and Agathodaemon as ancient prophets of its astral cult.

Chwolsohn’s thesis cut the knot in two. The true Sabians of the Qurʾān, he argued, were the Mandaeans of the southern Iraqi marshes — the baptizing community of the lower Tigris and Euphrates and the Khūzistān border, whose ritual life centers on living water and whose name the Arabic sources rendered as al-Mughtasila and Ṣubba. The Ḥarrānian pagans, on his reconstruction, were something else and later: a surviving Mesopotamian star-religion that appropriated the Qurʾānic name, around the year 830 and under pressure associated with the caliph al-Maʾmūn, to shelter an astral cult — with Hermes and Agathodaemon as its prophets — beneath a lawful label. On this account two distinct communities stood behind a single word: an authentic baptizing sect that was Sabian in the Qurʾān’s intention, and a borrowed identity adopted by the pagans of Ḥarrān as a survival strategy. The distinction let Chwolsohn keep both the scriptural text and the heresiographers’ reports without forcing them into contradiction, and it gave the Ḥarrānian astral religion its first sustained modern history.

Later scholarship has kept his documents while loosening his story. The neat conversion-by-decree narrative — the pagans adopting the name in a single legal maneuver at a datable moment — rests on a thin and partly anecdotal base, and the relation between the Ḥarrānians and the Arabic Hermes has been redrawn. The Ḥarrānian Hermes is now read more as a product of the Islamic era than as a simple survival from antiquity: the figure who appears in the Arabic doxographies as prophet of the star-worshippers belongs to the same ninth-century reconstruction that turned Hermes Trismegistus into the antediluvian Idrīs of the Qurʾān and the founder of the sciences — writing, astrology, alchemy, talismans, medicine — not to an unbroken pagan lineage reaching back through Hellenistic Egypt. On the present reading the Ḥarrānian community’s Hermes is downstream of that learned construction rather than its source: the star-worshippers, having taken a Qurʾānic name to live under Islam, were furnished a prophet to match by the same Abbasid doxographers who were giving the Arabic Hermes his prophetic genealogy. The cause and the effect, in other words, may run opposite to the way the nineteenth century read them. The identification of the Mandaeans with the Qurʾānic Sabians, too, is no longer treated as settled in the confident way Chwolsohn treated it — a question for the study of the Mandaeans on their own terms rather than as a footnote to Islamic law. The corpus he assembled has nevertheless never been replaced wholesale. Volume two, the Orientalische Quellen, prints forty-five primary extracts in Arabic with German translation — al-Nadīm, al-Masʿūdī, al-Shahrastānī, passages of Maimonides, and long stretches of the Ḥarrānian and Nabataean material — and that volume remains a working sourcebook, consulted where he left it, even by scholars who reject the frame around it.

What gave the book its durability was the discipline of its method, and that discipline belonged to a particular place and moment. The Imperial Academy of Sciences at St. Petersburg had become, by the 1850s, one of the great manuscript-rich centers of Oriental study, and Chwolsohn worked the way the best of that school worked: he assembled the dispersed testimonia, fixed the readings, and translated, before he argued. The argument could be wrong — it often is, in a field where every generation re-dates its texts — but the dossier of evidence, once made, outlasts the argument and serves the people who overturn it. His Sabian volumes did for the Ḥarrānian and Mandaean materials what a critical edition does for a single text: they made a scattered body of report into something a scholar could hold in two hands and disagree with precisely. Volume one had reconstructed the whole conceptual history of the word “Sabian” across Islamic heresiography before tracing the political and religious fortunes of the Ḥarrānian community itself, so that the documents in volume two arrived already set in a frame; the frame is what later scholarship has rebuilt, again and again, on the foundation he poured. That the disagreement, when it came, was sharp is a measure of how much there now was to disagree about. The reception of the Filāḥa in Maimonides — who treats the Nabataean Agriculture in the Guide of the Perplexed (III.29 and III.37) as the principal documentary witness to a pre-Mosaic Mesopotamian idolatry that the Law was given to rebut — reached the nineteenth century in part through the texts Chwolsohn gathered, and the Franco-Jewish counterweight of Salomon Munk’s contemporaneous edition of the Guide engaged Chwolsohn’s then-fresh thesis directly. The conversation he opened was wide before it was settled.

The Babylonian sequel

His sequel became a celebrated failure, and the shape of the failure is as instructive as the success. In 1859 he announced, in the Ueberreste der altbabylonischen Literatur in arabischen Übersetzungen, that the great Arabic agricultural encyclopedia known as the Nabataean Agriculture — the Kitāb al-Filāḥa al-Nabaṭiyya, attributed to Ibn Waḥshiyya — preserved genuine Babylonian literature thousands of years old, transmitted across the intervening centuries through a lost Aramaic intermediary. The claim was bold, philologically argued, and wrong. Ernest Renan answered from the side of Semitic linguistics, and Alfred von Gutschmid answered at length in 1861 with a hundred pages dismantling the antiquity thesis on internal evidence; Theodor Nöldeke, who had begun his own critique in 1869, returned in 1875 to fix a ninth-century-or-later date on the compilation and to point out the unmistakable Islamic-period idioms embedded in the supposedly ancient Aramaic substrate. The texts have been read ever since as compositions of early Islamic Iraq, antique in costume rather than in age — a pseudo-antiquity of the same family as the Arabic Hermetica, routed through seven invented Nabataean sages rather than through Hermes. The Nabataean Agriculture and the Sabian-Ḥarrānian astral religion belong, in current reading, to a single ninth-century Iraqi habit of anchoring revealed wisdom in a deep, conveniently irrecoverable past — the technique that also produced the Arabic Hermes and that runs through the wider field of Islamicate occultism and its astrology, alchemy, and talismanic sciences.

The episode dented his authority without erasing his usefulness, and the manner of its dismantling marks the moment philology came of age. What overturned Chwolsohn was not a rival authority’s verdict but a method: the close dating of a text by the grain of its own language, the catching-out of a forged antiquity by the idioms it could not help but use. Chwolsohn had argued bibliographically, from the testimony of later writers about what the texts contained; Gutschmid and Nöldeke argued from the inside of the Arabic and Aramaic, and the inside won. That he was on the losing side of the demonstration does not subtract from the demonstration’s value, and his collected materials remained the field on which it was fought.

Sources and scholarship

Chwolsohn’s two foundational works are both globally in the public domain (he died on 23 March 1911) and survive in clean digital scans. Die Ssabier und der Ssabismus, 2 vols. (St. Petersburg: Buchdruckerei der Kaiserlichen Akademie der Wissenschaften, 1856) — volume one a historical reconstruction running to some eight hundred pages, volume two the Orientalische Quellen of Arabic texts with German translation — is cataloged and scanned through the MENADoc Oriental collection at Halle at https://menadoc.bibliothek.uni-halle.de/ssg/content/titleinfo/1201868. The 1859 sequel, Ueber die Ueberreste der altbabylonischen Literatur in arabischen Übersetzungen (St. Petersburg: Imperial Academy; Mémoires de l’Académie Impériale des Sciences, 7e série, tome VIII, no. 2), is available as a full-view Google Books scan at https://play.google.com/store/books/details?id=5JleAAAAcAAJ, the form in which the Babylonian-antiquity argument that Renan, Gutschmid, and Nöldeke would refute is most directly read.

The decisive philological answers are equally accessible. Theodor Nöldeke’s “Noch Einiges über die ‘nabatäische Landwirtschaft’,” Zeitschrift der Deutschen Morgenländischen Gesellschaft 29 (1875), pp. 445–455 — the short, sharp text that fixed the ninth-century dating against Chwolsohn’s defense — is held in the complete ZDMG run digitized by MENADoc Halle at https://menadoc.bibliothek.uni-halle.de/dmg/periodical/structure/2; Alfred von Gutschmid’s earlier and longer dismantling, “Die Nabatäische Landwirtschaft und ihre Geschwister,” ZDMG 15 (1861), pp. 1–110, was reprinted in his Kleine Schriften, ed. Franz Rühl (Leipzig: Teubner, 1890). Ernest Renan’s Histoire générale et système comparé des langues sémitiques (Paris, 1855; 5th ed. 1878), whose later editions carry his polemical paragraphs against the antiquity thesis, is at Gallica (https://gallica.bnf.fr/ark:/12148/bpt6k6488950v).

The modern reassessment that placed Chwolsohn’s documents in a frame he would not have recognized runs through three indispensable studies, all in copyright and cited here as orientation: Tamara Green, The City of the Moon God: Religious Traditions of Harran (Leiden: Brill, 1992), which set the Ḥarrānian cult on a firm documentary footing; Jaakko Hämeen-Anttila, The Last Pagans of Iraq: Ibn Waḥshiyya and his Nabatean Agriculture (Leiden: Brill, 2006), which argues a both/and reading of the Filāḥa — genuine local Mesopotamian agronomy and folklore beneath a ninth-century pseudo-antique frame; and Kevin van Bladel, The Arabic Hermes: From Pagan Sage to Prophet of Science (Oxford: Oxford University Press, 2009), which reconstructs the Ḥarrānian Hermes as an Islamic-era product rather than an antique survival. The earlier scholarly apparatus — Goldziher on the Shuʿūbī literary milieu, Brockelmann’s bibliography, the Maimonidean reception edited by Salomon Munk — is the route by which the Sabian and Nabataean materials reached the twentieth century, and Chwolsohn’s volumes sit at the head of all of it.

The verdicts on his theses have shifted; the sources he collected are still consulted where he left them.
