The
Sinaiticus
Mystery
One famous Bible manuscript. Three trips to Sinai. A loan to Russia. Then Constantine Simonides claimed that he had helped make it.
What do the records prove—and what is still a claim?

Learning to read very old books
Constantin Tischendorf left his university work in Leipzig to study handwritten Bibles across Europe. In Rome he was allowed limited time with Codex Vaticanus. Rome was part of his research journey, not a stop made with Codex Sinaiticus.
Backed by recordsThe first Sinai visit
At St. Catherine’s Monastery, monks showed Tischendorf 129 leaves from an old Greek Bible. He left with 43 leaves. In 1846 he published them in Leipzig as Codex Friderico-Augustanus.
From a published accountA return, but not the main group
Tischendorf returned to the monastery. He obtained other manuscripts and one small Sinaiticus fragment, which he said had been used as a bookmark.
From a published accountThe larger part comes to Cairo
On his third visit, Tischendorf saw 347 leaves. They were moved to the monastery’s house in Cairo so he could study them. In September he signed a receipt describing the manuscript as a loan.
Backed by recordsA loan travels to Russia
The 347 leaves went to St. Petersburg for checking and publication. Tischendorf promised they would be returned if the monastery asked, while Russian letters also discussed a hoped-for gift to the Tsar.
Backed by recordsThe grand edition appears
Tischendorf’s facsimile edition was presented to Tsar Alexander II. The manuscript then stayed with the Russian Ministry of Foreign Affairs.
Backed by recordsDonation papers are signed
Ten years after the loan receipt, church leaders in Cairo and at Sinai signed acts donating the manuscript to the Tsar. The long delay and the politics around the decision are still discussed.

Open the sourcePut the discovery story to the test
Coincidence—or advance knowledge?
One remarkable discovery can happen by chance. A series of convenient events deserves closer examination. Which events were unexpected, which involved advance information, and which depend on one person’s account?
Ask the harder question: Does the discovery story withstand examination? Suspicion is a reason to investigate, not a finding of fraud. We cannot calculate “lottery odds” without knowing the circumstances.
1843 → 1844
Who pointed him toward Sinai?
The record: In his later account, Tischendorf dates his meeting with Pope Gregory XVI to May 1843, his voyage from Livorno to Egypt to April 1844, and his Sinai visit to May 1844.
Why examine it: What did he learn in Rome? Did anyone identify a particular manuscript or monastery before he travelled?
Check the objection and missing evidence
The strongest caution: His account describes a wider search through libraries and monasteries. Visiting Rome to study manuscripts does not establish that Rome sent him to Sinai.
What would help decide it: Dated letters, recommendations or instructions written before the first Sinai visit. A direction from Rome has not been established in the sources presented here.
1845 → 1856 → 1859
How unexpected was the later discovery?
The record: Uspensky described seeing the manuscript, including its New Testament, during his 1845 visit. His account appeared in 1856, before Tischendorf’s return in 1859.
Why examine it: Daniels and collaborators argue that this description and other contacts challenge a story of an entirely unexpected encounter in 1859.
Check the objection and missing evidence
The strongest caution: Information being available does not alone show that Tischendorf read it or knew where the leaves were. This later question cannot establish his knowledge before 1844.
What would help decide it: Compare the original Uspensky account with dated letters and records showing which reports reached Tischendorf before 1859.
The first 43 leaves
Does the rescue story stand up?
The record: Tischendorf later described finding leaves in a basket intended for burning. The manuscript project says no other record has been identified for his account of obtaining the first 43 leaves.
Why examine it: Daniels rejects the wastebasket story. Did a dramatic rescue story conceal what really happened?
Check the objection and missing evidence
The strongest caution: Lack of independent confirmation leaves a gap; it does not alone prove invention. The first leaves and the larger group need separate examination.
What would help decide it: Put his earliest private letters beside later published accounts and independent monastery records. Check where details agree, change or remain unsupported.
1859 → 1869
When did a loan become a gift?
The record: The 1859 receipt promised return when requested. Formal donation papers followed in 1869, amid a disputed church succession and Russian diplomacy.
Why examine it: That gap raises concrete questions about consent, pressure and how the manuscript was removed and retained.
Check the objection and missing evidence
The strongest caution: The later donation papers must also be considered. An ownership or handling dispute does not establish when the manuscript was made.
What would help decide it: Read the receipt, diplomatic letters and donation papers together, including the monastery’s position rather than only one participant’s account.
Three questions. Three separate answers.
Was the discovery story accurate? Was the manuscript handled honestly? When, and by whom, was it made? Evidence against one answer does not automatically settle the others.
Tischendorf’s account should face scrutiny even though it became widely accepted. Daniels’s case should face the same scrutiny. The colour, Simonides and Hermas arguments continue below.

Colour-calibration warning
A screen is not the parchment.
The project used shared standards, colour profiling and controlled lighting at four locations. It also chose a light-brown background as a compromise between readable ink and faithful parchment colour.
Camera settings, lighting, background, colour profile, web processing and your screen can all change what you see. A visible colour difference is worth investigating, but the online comparison alone cannot prove that someone darkened the manuscript.

Its limit: A carefully made digital image is still not the physical parchment, and a viewer’s screen adds another variable.
Open the source1862–1863 · the public dispute
Then Simonides spoke.
In a letter printed by The Guardian in September 1862, Constantine Simonides claimed he had written the codex more than twenty years earlier.
Mount Athos, 1839–40
Simonides said his uncle Benedict directed a new Bible manuscript at the monastery of St. Panteleemon on Mount Athos. He said it was meant as a gift for Tsar Nicholas I.
This is the place named in the historical claim: Mount Athos, not Mount Patmos.
Letters met letters
Samuel Tregelles dismissed the story. Simonides answered. Other writers challenged names, dates and handwriting. Henry Bradshaw said he had examined the codex and that Simonides’ description did not fit it.
The exchange continued into 1863. It was a real public debate, but a newspaper debate is not the same as a laboratory test.
The modern case for another look
Daniels and Pinto—in detail
These are their arguments, not settled facts. Each point is paired with a limit and a way it could be tested.
Daniels: colour, condition and physical testing
What he argues: Daniels and collaborators point to the lighter-looking 43 Leipzig leaves, the darker and more varied London leaves, the codex’s good condition, differences in ink images and the lack of published chemical age testing. They ask whether most leaves were made to look older after 1844.
What challenges it: The digitisation team used controlled lighting, colour profiles and a chosen background at four sites. A web image can shift colour. Palaeography, scribal work and the history of corrections also have to be explained.
What would test it: Calibrated physical measurements, non-destructive material analysis, open data and independent review would be stronger than screen comparisons.
Pinto: early stories, Hermas and Barnabas
What he argues: Pinto points to Tischendorf’s January 1859 letter saying he had heard stories told by Simonides before the larger group was shown to him. Pinto also connects Simonides’ real work with the Shepherd of Hermas and a disputed 1843 edition of the Epistle of Barnabas to unusual texts later found in Sinaiticus.
What challenges it: Critics dispute the dates and trustworthiness of some Simonides papers and editions. They also point to his record of disputed manuscripts and to the codex’s broader handwriting, correction and textual evidence.
What would test it: Locate and verify the early letters and editions, trace their custody, compare their readings openly and test the manuscript materials without damage.
Daniels and Pinto make a detailed case for Simonides. Here it remains a source-linked case to examine, not a verdict the reader must accept.
Original sourceSimonides letter reprinted in The Journal of Sacred Literature
September/October 1862
What it can show: Simonides said he wrote the codex at St. Panteleemon on Mount Athos in 1839–40 and explained how he believed it reached Sinai.
Its limit: The letter proves that he made the claim. It does not prove that the claim was true.

Open the sourceWhy Hermas matters
The Shepherd of Hermas problem
Codex Sinaiticus ends with early Christian writings outside the New Testament, including part of The Shepherd of Hermas.
Simonides supplied a Greek Hermas text
He brought three real leaves from Mount Athos and a copy of other leaves. The Greek text was published in Leipzig.
The copied part caused trouble
Scholars found serious problems. More original leaves were later found at Mount Athos and used to check what Simonides had copied.
Skill and warning at once
The episode shows that Simonides could handle rare Greek manuscripts. It also gives a reason not to accept every statement or copy from him without testing it.
The Hermas connection is important context. By itself, it does not prove Simonides made Codex Sinaiticus, and it does not make every question about him disappear.

The manuscript is now in four places
The main holdings are 347 leaves in London and 43 leaves in Leipzig, with leaves or fragments in St. Petersburg and at St. Catherine’s Monastery.
The 347 leaves left as a loan in 1859
Tischendorf signed a receipt. It called the codex monastery property and promised return when requested, while other letters spoke about a possible future gift.
Donation papers came ten years later
The formal acts of donation were signed in 1869, after a difficult church leadership dispute.
Simonides said he helped make the codex
In 1862 Simonides claimed that he wrote it in 1839–40 at St. Panteleemon on Mount Athos under the direction of his uncle Benedict.
Simonides knew Greek manuscripts and Hermas
He handled real manuscript leaves and supplied a Greek text of the Shepherd of Hermas. Daniels and Pinto argue this makes his Sinaiticus story harder to dismiss without examination.
Online leaf colours look different
Daniels and collaborators point to a lighter-looking Leipzig group and darker-looking London leaves and ask whether the larger group was treated later.
Image colour is not a direct chemical test
The project photographed pages in four places using colour profiles, controlled lighting and a compromise background. McGrane argues that the Leipzig images are over-bright. Screen colour alone does not prove later staining.
Simonides had a record of disputed manuscripts
Scholars challenged other material sold or copied by Simonides. His Hermas work shows both real skill and a reason to test his statements carefully.
The codex has features scholars date much earlier
Palaeography, scribal practice, corrections and the text’s history are part of the standard fourth-century dating. The modern forgery case must explain the whole object, not one photograph.
What tests would change the debate?
A clearly documented programme of non-destructive material analysis, open data and independent review could answer some physical questions. It would not, by itself, settle every question about ownership or motive.
A careful conclusion
There is a real mystery—but not every answer is equal.
The travels, the loan and the late donation papers are documented. Simonides really made his claim. Daniels and Pinto raise detailed questions. The standard fourth-century dating also rests on a much wider manuscript case than leaf colour alone.
A fair investigation should neither laugh away the claim nor turn a suspicious detail into proof. It should name the source, show its limit and ask what evidence could decide the point.
