A Bible Whose Own Colophons Are the Problem

Cairo Codex of the Prophets

Also called Codex Cairensis, Cairo Codex

A complete Prophets codex that says it was written by the father of the Masorete of the Aleppo Codex in AD 895 — a claim scholarship has been taking apart for seventy-five years, and which cannot now be tested because nobody will say where the book is.

The Whole Prophets, in One Volume

The Cairo Codex contains the Prophets entire — Joshua, Judges, Samuel and Kings, then Isaiah, Jeremiah, Ezekiel and the Twelve — running to 575 pages in the microfilm that is all most scholars have ever seen of it. It is reported to carry thirteen decorated carpet pages; that figure traces to a single popular source and neither Outhwaite nor any institutional record consulted here gives a count, so it is repeated as a report rather than printed as a fact. It is written on parchment in three columns, and it carries an unusually rich masorah, the marginal apparatus of counting-notes; a full edition of its biblical text was produced by F. Pérez Castro and colleagues in eight volumes between 1979 and 1992, and D. Lyons devoted a book to its masorah alone in 2000.

Its fame rests on its colophons rather than its text. One of them claims that the codex was written and pointed by Moses ben Asher at Tiberias, in the year the colophon dates as 827 after the destruction of the Second Temple — AD 894 or 895. That name is the reason anyone cares: Moses ben Asher was the father of the Aaron ben Asher who pointed the Aleppo Codex, so a manuscript from his hand would be the earliest witness to the family's work. Other colophons say the book was dedicated to the Karaite community in Jerusalem, and later given to the Karaite synagogue in Cairo, with a curse attached to anyone who sold, bought, altered or pawned it. The Crusader story usually told with them is not in them. No colophon says "Crusaders" and none says 1099; what one of them says is that the dedication was made "after its redemption", and reading those two words as a ransom from the Franks is a scholarly inference, made by P. Kahle and repeated since. B. Outhwaite, who has gone through every colophon in the book, is blunt about it: "There is no external history for this particular codex in the Middle Ages. Instead, these details have been derived from the ownership colophon... and from the dedication colophons." Another colophon names the man who paid for it: Jabez b. Solomon the Babylonian, who "had it made for himself to study it, out of [the proceeds of] his own labour, the toil of his hands, and the sweat of his brow."

Why It Was Believed, and Then Was Not

The early authorities took the colophon at face value. R. Gottheil, describing the codex in 1905, wrote that "there is absolutely no reason to doubt the data here given. The codex was written in the city of Tiberias by the well-known Masorite, Moses ben Asher (ninth century), in the year 897." P. Kahle, whose 1959 book on the Cairo Geniza shaped a generation's picture of the Hebrew Bible, was equally confident: "We are very well acquainted with the history of the Cairo Codex of the Prophets thanks to the colophons which it contains." On that footing the codex became one of the anchors of the whole Tiberian story.

J. L. Teicher broke the anchor in 1950, and did it in one sentence: "The Cairo codex was not written by Moses b. Asher.... The colophons with the names of Moses b. Asher and of Yaʿbeẓ b. Solomon were written by a scribe, who copied the colophon with M. b. Asher's name from another codex." Kahle argued back — his own case rested on the colophons being what they say they are, and Outhwaite records that he replied to Teicher on all four of the manuscripts he had built on them — and the field went with Teicher. C. Sirat states what is now the ordinary view, in Nicholas de Lange's published English of her book: "We read in a first colophon that Moses ben Asher wrote this codex of the entire Bible in 895-896 CE, in Tiberias. In fact, this colophon was probably that of the model copied by the scribe." It is worth seeing what kind of mistake that is. Nobody thinks somebody set out to deceive in the modern sense; a scribe copying an exemplar copied its colophon along with its text, the way a photocopy carries the original's date. Then, in the 2011 revision of his handbook, I. Yeivin added physical evidence. That revision is in Hebrew and has not been translated; the English below is Outhwaite's, and he says so: "Some researchers have challenged the authenticity of the colophon of the manuscript, considering it to have been written in the 11th-century. Chemical analysis (C14) carried out in 1996 supports this opinion." A loose fragment had been taken away and dated, and it agreed with Teicher.

The Book Nobody Can Find

B. Outhwaite, who heads the Genizah Research Unit at Cambridge, published a study of all the codex's colophons in 2025 and went further than the dating question. His argument is that the dedication colophons — the ones carrying the Karaite dedication in Jerusalem — are themselves later additions: "While the dedications draw on information from the ownership colophon, they betray stylistic incongruities that strongly suggest they are later additions and not genuine medieval colophons, in particular in their addition of new information about the donor, his creed and his intentions." His summary of what is left is short enough to quote whole: "I think we can really only reliably say the following at this stage: 1. The codex was commissioned by Jabez b. Solomon (ownership colophon), who was of Babylonian heritage. 2. The codex was dedicated to the Karaite synagogue in Cairo sometime in the fifteenth century (probably), by a dignitary, David b. Yefet." To which he adds that the C14 result makes an origin in eleventh-century Egypt likely. What survives that scrutiny is less than the story usually told, and it is not nothing: Outhwaite keeps the ownership colophon and the fifteenth-century Cairo dedication, and it is the Tiberias attribution and the Jerusalem dedications that he thinks were copied or written in later. The Crusader journey he treats differently again, and it is worth being exact, because he does not date it late — he rejects it. Of the colophon everyone has read that way he writes: "the book was redeemed from the Crusaders. But a tremendous leap needs to be taken to read it this way" — the hand is at least two centuries later than 1099, and "as is far more likely, the reference has nothing to do with the Crusader seizure of books." His own preferred explanation is a Mamluk one: the same colophon speaks of the Cairo synagogue being rebuilt and allows the book to be removed "out of need", and in fifteenth-century Cairo synagogues were being closed, confiscated and torn down, so a redemption of the book from that is the likelier occasion. Of the repair note dated 1129-1130 that others have used to date the ransom, he says flatly: "There is no reason at all to connect it with the redemption of the book, and especially not with the Crusaders."

And it cannot be checked. Outhwaite's own footnote says why, and it is the reason this article carries no shelfmark: "Its whereabouts are currently unknown or, by those who do know, unacknowledged. I am reliant on microfilm images of the codex that were produced when it was still in the care of the Karaites in Egypt. Since then, it is widely suspected that it, along with one or two others... has made its way to Israel—although this is not publicly acknowledged. The status of the book should be revealed and regularised." That is a working scholar saying, in print, that one of the most important Hebrew manuscripts in existence has disappeared from view. He is also careful not to overclaim against those who still defend the old attribution: on the dating he says only that "the further technical analysis that might help convince any lingering doubters will not be possible until the codex emerges legally into the light." The one thing anybody can consult is a poor black-and-white microfilm made in 1971, which does not even include the illuminated pages. It is on the open web, and Outhwaite links to it himself.
