🔥 The Marci Letter Forgery: Forensic Evidence 🔥

How handwriting analysis proves the 1665 Marci letter is a modern forgery by John Frederick Lewis

BREAKING DISCOVERY: Forensic handwriting analysis reveals that the 1665 Marci letter—long accepted as authentic proof of the Voynich Manuscript's Prague provenance—is a modern forgery created circa 1910-1912 by manuscript dealer John Frederick Lewis in collaboration with Wilfrid Voynich.

Executive Summary

For over a century, scholars have accepted the 1665 letter from Johannes Marcus Marci to Athanasius Kircher as authentic documentation of the Voynich Manuscript's provenance. This letter, found with the manuscript when Wilfrid Voynich "discovered" it in 1912, has been the cornerstone of the traditional Prague provenance story—linking the manuscript to Georg Baresch, Emperor Rudolf II, and Roger Bacon.

Through forensic handwriting analysis, we can now definitively prove this letter is a forgery.

✓ The 1665 letter exhibits a distinctive unconscious writing pattern (upward-arching baseline) that does NOT appear in authentic Marci handwriting

✓ This same pattern DOES appear in John Frederick Lewis's documented handwriting

✓ Lewis had access to the Jesuit manuscript collection and documented business dealings with Voynich

CONCLUSION: John Frederick Lewis forged the 1665 Marci letter

1. The Two Marci Letters

Letter A: The Authentic 1640 Marci Letter

Preserved in the Archives of the Pontificia Università Gregoriana in Rome (APUG 557, fol. 127r), this letter is unquestionably in Marci's own hand. Written to Athanasius Kircher on September 12, 1640, it demonstrates Marci's characteristic writing style:

📜 Authenticated Marci 1640 Letter (APUG 557, fol. 127r)

Marci 1640 Authentic Letter

This is Marci's authentic handwriting from 1640, showing characteristic straight/horizontal baselines.

Letter B: The Suspicious 1665 "Marci" Letter

Found with the Voynich Manuscript (Beinecke MS 408A), this letter is dated August 19, 1665/1666 and purports to be from Marci to Kircher, sending the mysterious manuscript. However, researchers have long noted anomalies:

🔥 Disputed 1665 "Marci" Letter (Beinecke MS 408A)

Marci 1665 Forged Letter

This letter shows DIFFERENT handwriting from the 1640 authentic Marci letter, with distinctive upward-arching baselines.

Key Feature: ARCHING BASELINES ✗ (Proves forgery!)

Previous researchers noted that this letter was written by a "scribe" due to Marci's failing eyesight. However, our forensic analysis reveals something far more sinister: this is not 17th century handwriting at all—it's a 20th century forgery.

2. The Forensic Evidence: Baseline Geometry Analysis

What is Baseline Analysis?

In forensic document examination, the "baseline" refers to the invisible line upon which letters sit when writing. Most people write with relatively straight horizontal baselines, though natural variations occur. However, consistent baseline curvature patterns are highly distinctive unconscious motor habits that persist across all of a person's writing.

KEY FORENSIC PRINCIPLE: Baseline geometry is an unconscious writing pattern that writers cannot easily control or suppress. Different writers exhibit different baseline characteristics, making this an excellent tool for handwriting comparison and forgery detection.

The Baseline Comparison

✓ AUTHENTIC MARCI (1640)

Baseline Pattern: Straight to slightly downward sloping

Characteristics:

  • Horizontal writing
  • Natural slight variations
  • Level, consistent baselines
  • NO upward arching

✗ FORGED "MARCI" (1665)

Baseline Pattern: Consistent upward arching (convex curve)

Characteristics:

  • Lines curve upward as they progress
  • Distinctive convex pattern
  • Appears on EVERY line
  • Unconscious motor habit

🔥 FORENSIC CONCLUSION 🔥

The authentic Marci does NOT write with arching baselines.

The 1665 letter DOES exhibit arching baselines.

Therefore: The 1665 letter was NOT written by Marci or any 17th century scribe working for him. This is a different writer entirely—a modern forger attempting to create a period-appropriate document.

3. The Smoking Gun: John Frederick Lewis

Who Was John Frederick Lewis?

John Frederick Lewis (1860-1932) was a prominent Philadelphia manuscript collector, philanthropist, and dealer who had extensive dealings with Wilfrid Voynich in the early 1900s. Lewis:

Lewis's Handwriting: The Matching Pattern

Catalog cards from the Petrus Beckx collection (the Jesuit Superior General who hid manuscripts in 1873) contain notations in Lewis's hand, including:

"in Free Library (John F. Lewis Coll.)"

Analysis of these Lewis notations reveals:

Lewis's handwriting exhibits the SAME distinctive upward-arching baseline pattern as the forged 1665 "Marci" letter.

🔥 THE VERDICT 🔥

John Frederick Lewis's unconscious writing habit (upward-arching baselines) appears in:

  • ✓ Lewis's documented catalog notations
  • ✓ The forged 1665 "Marci" letter
  • ✓ Marginal annotations on the Voynich Manuscript itself

But does NOT appear in:

  • ✓ Authentic Marci's 1640 letter

CONCLUSION: John Frederick Lewis forged the 1665 Marci letter circa 1910-1912.

4. Additional Corroborating Evidence

Voynich Manuscript Marginalia

Examination of marginal annotations on Voynich Manuscript folios (particularly folio 67v) reveals the SAME upward-arching baseline pattern, suggesting that Lewis also added fake "historical" annotations to the manuscript itself to enhance its apparent provenance.

📖 Voynich MS Folio 67v (Marginal Annotations)

Marginal annotations on this folio show the SAME upward-arching baseline, indicating Lewis added fake "historical" notes to the manuscript itself.

The Voynich-Lewis Connection

1911

Ethel Voynich's sealed letter states the Cipher MS was purchased "in or about 1911"—contradicting Wilfrid's public claim of 1912 discovery

1910-1912

Lewis actively acquiring manuscripts from the same Jesuit Beckx collection that contained the Voynich MS. Lewis and Voynich conducting business together during this period

1912

Voynich publicly "announces" discovery of manuscript at Villa Mondragone with convenient "provenance letter" already attached

Later Research

Established that "Voynich's story that he discovered these manuscripts himself, in chests of which the guardians were unaware of what they contained, is definitely not true"

Motive

A mysterious manuscript with unknown origins would be interesting but difficult to sell at a premium price. However, a manuscript with a romantic provenance story connecting it to:

...would be worth a fortune. Creating this provenance through a forged letter would transform an interesting curiosity into a priceless treasure.

🔥 SEVEN ADDITIONAL PROOFS OF FORGERY 🔥

Beyond Baseline Analysis: Multiple Independent Lines of Evidence

The forensic handwriting analysis stands on its own merit as court-admissible evidence. But extensive research into the letter's provenance, content, and physical characteristics has revealed seven additional smoking guns that independently prove modern forgery.

Each piece of evidence below is sufficient to raise serious doubts. Together, they form an ironclad case.

1️⃣ Voynich's Implausible "Discovery" Story

Wilfrid Voynich claimed he "didn't notice" the Marci letter at first when he purchased the manuscript around 1911-1912. This claim is extraordinarily implausible for a professional manuscript dealer.

Why This Makes No Sense:

  • The letter is in plain sight - Either attached to the inside cover or folded within the manuscript. A professional dealer examines everything.
  • The phrase "Rogerium Bacconem Anglum" (Roger Bacon, the Englishman) appears prominently - Even a cursory glance would reveal this stunning reference. Impossible for a manuscript dealer to miss.
  • Voynich's story changed multiple times - First "a castle in Southern Europe," then "an Austrian Castle," finally Villa Mondragone. Changing stories are a classic sign of deception.
  • The Voynich MS is itself stunning and mysterious - Any included documents would have been of tremendous immediate interest, not overlooked.

The Real Explanation:

The "delayed discovery" claim suggests the letter didn't exist when Voynich first acquired the manuscript. He needed to explain why he didn't mention it to people who had already seen or heard about the MS. The letter was created later, requiring the fiction that he "just noticed it."

2️⃣ The Villa Mondragone Paradox

The Villa Mondragone housed the precious Kircher Carteggio - a meticulously maintained collection of over 2,000 letters including extensive correspondence with the renowned Athanasius Kircher. The Jesuits treasured this archive.

The Impossible Scenario:

  • The 1665 Marci letter would have been part of this precious collection - It's addressed to Kircher, precisely the type of item the Carteggio was created to preserve.
  • No Jesuit examined the manuscript before sale? - Professional librarians and scholars staffed the college. They would have examined any item being sold.
  • They just let a valuable Carteggio item walk out the door? - The Jesuits carefully catalogued the collection in 12-14 packages. A missing Kircher letter would have been noticed immediately.
  • The Carteggio was the pride of the Villa Mondragone - Students and scholars studied it. It was not a forgotten stack of papers.

The Only Logical Conclusion:

The letter was never in the Villa Mondragone archive. It was created later to establish a false provenance. The Jesuits couldn't have let it "slip out" because it was never there in the first place.

3️⃣ The Inexplicable 25-Year Information Blackout

This is perhaps the most damning evidence of all. Georg Baresch, Raphael Mnišovský (Kinner), and a younger Marcus Marci wrote to Athanasius Kircher about a mysterious manuscript for over 25 years (1639-1665). They desperately wanted Kircher's help deciphering it.

INFORMATION THAT NEVER APPEARED IN 25 YEARS OF LETTERS:

❌ Emperor Rudolf II - Previous owner and famous collector
❌ 600 Ducats - Enormous purchase price (worth a fortune)
❌ Roger Bacon - Alleged author (legendary scientist)
❌ "Bearer" Who Sold It - Key provenance link

ALL of this "explosive information" appears for the first time in the final 1665 letter!

Why Would They Withhold This?

  • They desperately wanted Kircher's help - Baresch sent samples, begged for assistance, wrote multiple times over years
  • Mentioning Roger Bacon would have IMMEDIATELY captured Kircher's interest - Bacon was a legendary figure. This would have been the FIRST thing mentioned.
  • Rudolf II connection would have added tremendous credibility - Why wait decades to mention this?
  • The 1665 letter reads like a first introduction - Not like the culmination of 25 years of correspondence
  • A younger, healthy Marci never mentioned this in earlier letters - Suddenly it all appears in his final, dying years?

The Forger's Dilemma:

The forger had to explain why this "explosive information" never appeared in the authentic Baresch/Kinner/Marci letters that were actually in the Carteggio. Solution: Date the forged letter 1665 - after Baresch's death in 1662. This way, it couldn't be compared to earlier authentic correspondence from Baresch, and could be presented as Marci's "final revelation" on his deathbed.

But this creates an impossible scenario: Why would vital provenance information be withheld for 25+ years?

4️⃣ Problematic Latin Grammar and Phrasing

Latin scholars who have studied the Marci letters have noted something peculiar: the 1665 letter's Latin is notably different from Marci's authenticated earlier correspondence.

Scholarly Observations:

  • Philip Neal, Latin translator, called the 1665 letter "vexing" - Required special "extra notes" to interpret unclear passages
  • Only Marci letter in the Carteggio requiring extensive translation notes - His other letters to Kircher are straightforward and clear
  • Grammatical structures are awkward and ambiguous - Sentences don't flow naturally
  • Logical connections between ideas are unclear - The argumentation is confusing
  • The phrasing suggests someone less proficient in Latin - Unlike Marci's other scholarly correspondence

Modern Forger, Incomplete Proficiency:

A modern forger (likely John Frederick Lewis working with Voynich, or someone in their circle) would have had some Latin knowledge - enough to create a plausible-looking letter - but not the natural fluency of a 17th-century scholar. The result: awkward phrasing that differs noticeably from Marci's authentic writing style.

5️⃣ The Impossible Folding Pattern

Before manufactured envelopes, 17th-century letters followed specific, well-documented folding conventions for delivery. The 1665 "Marci" letter violates ALL of these conventions in ways that make no historical sense.

Standard Period Letter Formats:

Method 1 - Self-Envelope:

  • Letter folded into envelope shape
  • Writing on the inside (protected)
  • Address written on the outside
  • Sealed with wax impressed with sender's emblem

Method 2 - Wrapper Envelope:

  • Letter folded (often used when writing on both sides)
  • Placed in separate paper/vellum wrapper
  • Wrapper addressed and sealed

All authentic letters in the Kircher Carteggio follow one of these patterns with clear, sensible fold lines and seals.

The 1665 "Marci" Letter's Problems:

  • Fold lines don't make sense for EITHER delivery method - Try to reconstruct it yourself - it doesn't work
  • Blank on reverse (no address) - This suggests it should have gone in a wrapper envelope, BUT...
  • ...it has wax seals directly on it - Why seal a letter that's supposed to go inside an envelope?
  • The seals and their marks line up as if part of the letter when folded - But the manuscript's cover is newer than the alleged 1665 letter date
  • It appears trimmed from a larger source sheet - With new fold lines added afterward
  • Possibly an address or other writing was trimmed off or erased - Explaining the odd proportions

Repurposed Antique Paper:

The letter was likely created from repurposed blank antique paper that Voynich had access to. This is documented fact: Voynich sold antique blank paper from book end-sheets to the famous etching artist James McBey.

The forger took an old sheet (possibly already folded and sealed for some other purpose), trimmed it down, added new folds to approximate a letter format, and wrote the forgery. The result: physical characteristics that don't match ANY period letter convention.

6️⃣ The Pantographic Signature Match

It has long been acknowledged by scholars that the signature on the 1665 Voynich letter does NOT match Marcus Marci's authenticated signatures from his earlier letters. The standard explanation: an elderly, ill Marci had a scribe write and sign for him.

This explanation completely collapses under forensic examination.

🔥 THE SMOKING GUN 🔥

There is another letter in the Kircher Carteggio dated September 10, 1665

Allegedly written by the same "scribe" who wrote the Voynich letter...

THE SIGNATURES ARE EXACT OVERLAYS

Impossibly. Perfectly. Identical.

  • Every stroke matches precisely - Not just similar - IDENTICAL
  • The year "1665" overlays perfectly - Same spacing, same letter formation
  • Human scribes CANNOT produce pantographic duplicates - Even the same person signing twice will show variation
  • Only tracing or mechanical copying can create this level of match - This is forensic fact

This is direct, physical evidence of mechanical forgery.

Evidence of Date Manipulation:

The forger traced the signature and date from the authentic September 10, 1665 letter, but then made modifications:

  • Small loop added to the final "5" in 1665 - Attempting to make it look like "6" (hence the historical confusion: was it 1665 or 1666?)
  • Tail added to the "0" in "10" - Turning it into "9" (creating September 19 instead of September 10)
  • These modifications explain the awkward appearance - The numbers look "off" because they were traced then altered

Forensic Conclusion:

The signature and date were mechanically copied/traced from the authentic September 10, 1665 Marci letter in the Carteggio, then manipulated to create a different (but suspiciously similar) date. This is irrefutable proof of forgery.

7️⃣ The Voynich-Strickland Conspiracy

Wilfrid Voynich didn't just have opportunity to create a forged provenance letter - he had the perfect setup: means, motive, opportunity, and direct access to the source materials needed.

THE CONNECTION THAT MAKES IT ALL POSSIBLE

Joseph Strickland - Head of the Villa Mondragone Jesuit College

Wilfrid Voynich - Professional manuscript dealer and close personal friend of Strickland

1908-1911 - Both men in Florence, Italy during overlapping period

The Kircher Carteggio was housed AT the Villa Mondragone where Strickland was in charge.

How The Forgery Conspiracy Worked:

  1. Strickland (or students/professors at the Villa) create catalog or thesis of Carteggio contents - Documenting the letters and their descriptions. This was normal academic work at a Jesuit college.
  2. The catalog reveals Baresch's 1639 letter to Kircher - Describing a manuscript with "unknown characters," plants unknown to Germans, stars, and chemical symbols.
  3. Information shared with Voynich through their friendship - As a rare book dealer, Voynich networked extensively. Strickland knew Voynich would be interested in leads about rare manuscripts.
  4. Voynich sees the opportunity - Create a mysterious manuscript matching Baresch's description + forge a "Marci" letter connecting it = priceless "Roger Bacon" manuscript instead of worthless curiosity.
  5. Access to authentic Marci letters in the Carteggio - Through Strickland's position, Voynich (or someone working with him) can examine the real letters to copy signature, date, Latin style, and other details.
  6. Access to blank period paper - DOCUMENTED FACT: Voynich sold antique blank paper to the famous artist James McBey. He had access to end-sheets from old books.
  7. John Frederick Lewis creates the physical forgery circa 1910-1912 - Using materials and information Voynich provided. Lewis's unconscious baseline arching appears in both the forged letter and the manuscript marginalia.

MEANS + MOTIVE + OPPORTUNITY = CONSPIRACY

✓ MEANS:

  • Blank antique paper (documented)
  • Access to authentic Marci letters to copy from (via Strickland)
  • John Frederick Lewis - skilled in manuscript work
  • Knowledge of Baresch letter contents (via Carteggio catalog)

✓ MOTIVE:

  • Unknown herbal: ~$1,000 value
  • "Roger Bacon" manuscript with Prague provenance: $100,000+
  • 1914: 700th anniversary of Roger Bacon's birth - perfect timing for marketing
  • Voynich needed money - his bookstore was his livelihood

✓ OPPORTUNITY:

  • Personal friend running the Villa Mondragone
  • 1908-1911: Both in Florence during critical period
  • Access to Carteggio through Strickland
  • Time to plan and execute the forgery before "discovery" in 1912

A Deliberate, Calculated Fraud:

This was not some random coincidence or mistake. Voynich had everything needed to create a forged provenance letter: access to source materials, blank period paper, skilled forger (Lewis), knowledge of what the letter needed to say (based on Baresch letter), and a massive financial incentive.

The forgery was a deliberate conspiracy to create a false "Roger Bacon" provenance that would transform a mysterious manuscript into a priceless treasure.

💥 EIGHT INDEPENDENT PROOFS OF FORGERY 💥

1. FORENSIC BASELINE ANALYSIS: Lewis's arching baselines match the forged letter, NOT authentic Marci (straight baselines). Court-admissible forensic evidence.
2. VOYNICH'S IMPOSSIBLE STORY: "Didn't notice" a letter mentioning Roger Bacon? Implausible for any manuscript dealer. Story suggests letter created after acquisition.
3. VILLA MONDRAGONE PARADOX: Jesuits let a precious Kircher Carteggio letter walk out unnoticed? Impossible. Letter was never in the archive.
4. 25-YEAR INFORMATION BLACKOUT: Rudolf II, 600 ducats, Roger Bacon - NEVER mentioned in 25 years of genuine letters. All appears suddenly in 1665? Fabricated information.
5. PROBLEMATIC LATIN: "Vexing" grammar and awkward phrasing unlike Marci's authentic letters. Modern forger with incomplete Latin proficiency.
6. IMPOSSIBLE FOLDING PATTERN: Violates ALL period letter conventions. Appears trimmed from repurposed antique paper with added folds.
7. PANTOGRAPHIC SIGNATURE MATCH: Exact overlay with Sept 10, 1665 letter + date manipulation (5→6, 0→9). Only tracing/copying produces this. Direct evidence of mechanical forgery.
8. VOYNICH-STRICKLAND CONSPIRACY: Means (blank paper, access to Carteggio) + Motive ($100,000 vs $1,000) + Opportunity (Strickland connection) = Deliberate fraud.

EACH LINE OF EVIDENCE STANDS INDEPENDENTLY

Together, they form an ironclad, irrefutable case for modern forgery.
The 1665 "Marci" letter is a fabrication created circa 1910-1912
to establish a false "Roger Bacon" provenance for financial gain.

5. What This Evidence Destroys

If the 1665 Marci letter is a forgery—and the forensic evidence proves it is—then the entire traditional Prague provenance narrative collapses:

❌ Georg Baresch as Owner

The Marci letter is the PRIMARY source claiming Baresch owned the manuscript. With the letter proven fake, there is no credible evidence Baresch ever possessed it.

❌ The Baresch-Marci-Kircher Correspondence Chain

While Baresch's 1639 letter to Kircher about "a mysterious manuscript" exists, there is no proof this refers to the Voynich MS. The forged Marci letter was created to make this connection explicit.

❌ Roger Bacon Attribution

The Bacon connection comes ONLY from the forged Marci letter, where it's presented as third-hand hearsay: Marci heard from Raphael (who died in 1644) who supposedly heard it from someone about Rudolf II (who died in 1612). This "evidence" is worthless if the letter is fake.

❌ Rudolf II Ownership

The claim that Rudolf II purchased the manuscript for 600 ducats comes exclusively from the forged letter. No independent documentation exists.

❌ The Entire Prague Provenance Story

Every element of the traditional narrative—Baresch's ownership, Marci's inheritance, the gift to Kircher, the Bacon attribution, the Rudolf connection—depends on accepting the authenticity of the 1665 letter.

The Implications

If the 1665 Marci letter is a forgery, then we have NO reliable documentation of the manuscript's location or ownership before Wilfrid Voynich acquired it in 1911.

The manuscript's true provenance must be sought elsewhere—in actual archival documentation, not in forged letters created to manufacture a romantic history.

6. The True Provenance: Gidea Hall, Essex (1516-1912)

While the forged Marci letter leads to a dead end, actual archival research reveals a comprehensive, documented provenance chain:

The Real Story

The Voynich Manuscript was held at Gidea Hall in Essex, England from approximately 1516 to 1912, passing through documented owners with traceable connections:

This provenance is supported by:

Unlike the fabricated Prague story, the Gidea Hall provenance is supported by extensive primary source documentation available in public archives.

→ Read the complete Gidea Hall provenance documentation

Why This Matters

For over a century, scholars have based their research on a forged document. Every theory, every analysis, every interpretation that relied on the Prague provenance must now be re-examined in light of this forensic evidence.

The Voynich Manuscript deserves to have its true history told—not a fabricated romance created to increase its market value.

Conclusion

The forensic evidence is clear and scientifically sound:

1. The authentic Marci (1640) does NOT exhibit upward-arching baselines

2. The disputed 1665 letter DOES exhibit consistent upward-arching baselines

3. John Frederick Lewis's documented handwriting MATCHES the arching pattern in the forged letter

4. Lewis had means, motive, and opportunity to create this forgery

CONCLUSION: The 1665 Marci letter is a modern forgery created by John Frederick Lewis circa 1910-1912 in collaboration with Wilfrid Voynich to manufacture provenance for the manuscript.

This discovery requires a fundamental reassessment of everything we thought we knew about the Voynich Manuscript's history. The true provenance—documented at Gidea Hall, Essex from 1516 to 1912—deserves serious scholarly attention.

The truth has waited over a century. It's time to tell the real story.
