(1) Allan Massie, She Wanted to Break Free; Newsly decoded ncorrespondence reveals that Mary, Queen of Scots, was involved in various plots to free her from jer English imprisonment. Wa;; Street Journal, Apr 3, 2025, at page A15
(book review on Jade Scott, Captive Queen; The decrypted history of Mary, Queen of Scots. Pegasus, Oct 24, 2024)

Quote: "Mary was tried, found guilty * * * and sentenced to death. [Queen[ Elizabeth, reluctant to execute an anointed queen, asked Mary's jailer Amyas Paulet to dispose her quietly. Paulet indigently refused. At last Elizabeth signed the death warrantthat ad been in her nightmares for years; it [warrant] was quickly whisked away before she could change her mind.

My comment: This book is about the HISTORY of Mary, from the viewpoint of "decrypted history." The review itself says little about the decrypted letters. Hence there is no need to read the book review.

Quote:

(a) "The 57 secret letters [that are reported to be decoded], from Mary Stuart to the French ambassador to England between 1578 and 1584 [judging from the years, which were remote from excution, the letters had nothing with the execution -- not to mention that Queen Elizabeth I was unaware of existence of most of the 57 (except those letters also found in England)/ As )1) states above, these letters at most sought freedom], were written in an elaborate code. The findings come 436 years after Mary's death by execution on February 8, 1587.

"Most of the letters were kept in the Bibliothèque Nationale de France in Paris, mainly in a large set of unmarked documents that were also written in cipher — special graphical symbols. The documents were listed as dating from the first half of the 16th century and thought to be related to Italy.

"Then, a trio passionate about cracking historical ciphers stumbled upon the documents.

"George Lasry, a computer scientist and cryptographer from France; Norbert Biermann, a pianist and music professor from Germany; and The 57 secret letters, from Mary Stuart to the French ambassador to England between 1578 and 1584, were written in an elaborate code. The findings come 436 years after Mary’s death by execution on February 8, 1587.

Most of the letters were kept in the Bibliothèque Nationale de France in Paris, mainly in a large set of unmarked documents that were also written in cipher — special graphical symbols. The documents were listed as dating from the first half of the 16th century and thought to be related to Italy.

"Then, a trio passionate about cracking historical ciphers stumbled upon the documents.

"George Lasry, a computer scientist and cryptographer from France; Norbert Biermann, a pianist and music professor from Germany; and Satoshi Tomokiyo a physicist and patents expert from Japan, all worked together to find the truth behind the documents a physicist and patents expert from Japan, all worked together to find the truth behind the documents.

(b) "Once the researchers began working through the unique ciphers, they quickly realized the correspondence was written using French, and there was nothing Italian about it.

"The team spied verbs and adverbs that used a feminine form, mentions of captivity — and a keyword: Walsingham. Sir Francis Walsingham was Queen Elizabeth I's secretary and spymaster. Together, all signs pointed to the fact that the team may have found letters of Mary Stuart thought lost for centuries.

"The results were published Tuesday in the journal Cryptologia."

(c) "[The finding of this paper in Cryptologia:] The ciphers were homophonic, meaning each letter of the alphabet could be encoded using several cipher symbols, according to the researchers. This practice ensured that certain symbols weren’t used too frequently. The text also included dedicated symbols to signify common places, words and names.

Note:
(a) Satoshi TOMOKIYO 友清 理士 (1967- ; male; ja.wikipedia.org says he is a nostorian and translater, without mention of decoding)
(b) The verb decipher in Japanese: 暗号解読.
(c) There is no need to read the rest of this CNN report. But do view a table of codes with black codes and pink (deciphered) letters on grayish background. The top French word "prochaine" is feminine form of adjective masculine prochain meaning "upcoming."

(3) The direct cause of Mary's execution was Babington Plot
https://en.wikipedia.org/wiki/Babington_Plot
("The chief conspirators were Anthony Babington and John Ballard. Babington, a young recusant, was recruited by Ballard, a Jesuit priest who hoped to rescue the Scottish queen. * * * On 7 July 1586, the only Babington letter that was sent to Mary was decoded by [Thomas] Phelippes[, Francis Walsingham's decoder]. Mary responded in code on 17 July 1586 ordering the would-be rescuers to assassinate Queen Elizabeth")

Note:
(a) "In Under the Molehill – an Elizabethan Spy Story, John Bossy writes that a secret correspondence with her associates and allies, prior to its compromise in mid-1583 * * * To our great surprise, those letters turned out to be from Mary Stuart, from 1578 to 1584, addressed mostly to Michel de Castelnau, seigneur de La Mauvissière, the French ambassador in London between 1575 and 1585. We also found in British Archives [official name: The National Archives] plaintext copies of seven of those deciphered letters, from 1583 to 1584, which were apparently leaked to Francis Walsingham * * * In the BnF catalog, the ciphertext documents are merely listed as 'Pièce en chiffre' or 'dépêches chiffrées' * * * In 1558, she married the Dauphin Francis, who succeeded to the French throne in 1559 [as Francis II, who died a year later in 1560] * * * [as mother of French kings Francis II and his younger brothers Charles IX and Henry III,] Catherine de' Medici was her [Mary Stuart's] mother-in-law."

(b) "Mary married Henry Stuart, Lord Darnley [of Scotland] in 1565, but by the time she gave birth to a son, future James VI, in 1566, she had been disillusioned with Darnley. Her third marriage with the Earl of Bothwell, too soon after the extraordinary death of Darnley, alienated the Scottish people because Bothwell was suspected by many to have been involved in his murder. Protestant nobles turned against Mary and imprisoned her in Lochleven, a castle on an island in the middle of a lake, where she was forced to abdicate in favor of her infant son in 1567. * * * Descended from Henry VIII’s sister, Mary had a claim to the English throne, and there were many Catholics who believed that Elizabeth was an illegitimate queen, because, in their eyes, Henry VIII's divorce of Catherine of Aragon and his marriage with Anne Boleyn, Elizabeth’s mother, were void, and Mary was the rightful queen of England.

—---------Apr 7—-----This is a rejoinder.

(1) I hold a PhD in biology. In my first quarter (at the time, the university, my alma mater, had a quarter system where an academic year was divided into four quarters), the chairman of the department told the incoming students that a PhD should assess a research paper independently from authors' claims. I mulled this Cryptologia for two nights. For convenience of discussion, I switch the URL of the Cryptologia paper from HTML (the top URL next; the choices are found in this URL underneath the title in green rectangular tabs) to pdf (the bottom URL), so that I can cite pages.

George Lasry, Norbert Biermann, & Satoshi Tomokiyo, Deciphering Mary Stuart's Lost Letters from 1578-1584. Cryptologia, 47: 101 (online publication Feb 8, 2023; in print Mar 4, 2023)

(2) In this paper:
(a) Regarding Francis Walsingham's codebreaker Thomas Phelippes. This paper at page 106, note 30 stated, "A gifted codebreaker as Phelippes was, he was sometimes helped in his work by the capture of cipher keys." (sources omitted)
(b) section "7. Conclusion: * * * While at least one letter in cipher [out of the 57 found in Bibliothèque nationale de France (BnF)] seems to have been intercepted and deciphered in late 1583 by Phelippes,[note351] we did not find the key for the Mary-Castelnau cipher among the dozens of cipher keys related to Mary held in British archives, nor did we find any document encrypted with this cipher in those archives."  pages 190 (heading)-191 (text).
(c) the keys (to this set of code in this paper):
(i) page 110: "Based on the partial decipherment of several documents, we were able to attribute the letters to Mary, Queen of Scots, addressed to Castelnau, the French ambassador. By reviewing the text of previously-known letters between Mary and Castelnau, we found several documents matching our decipherments, enabling us to determine or validate the meaning of other symbols. Finally, we identified symbols representing names, places, and the twelve months of the year and completed the transcription and decipherment of all the documents.
(ii)
(A) page 122: section "4.6. Recovering the symbols for names and places" (heading)
(B) page 124: section "4.7. Recovering the symbols for the months" (These two sections explained how the paper decoded these symbols, which are collected in the next section as key(s) to these 57 letters.
(C) page 125: section "4.8. The complete reconstructed Mary-Castelnau cipher
(iii) all Mary's letters (coded or plaintext; known before and after publication of this Cryptologia paper -- the former was numbered by Bossy) was found in Appendix C (starting at page 200): "Letters originally sent in cipher are highlighted" or shaded.


(3) Though this paper claimed, at Note (2)(b) that "we did not find the key for the Mary-Castelnau cipher among the dozens of cipher keys related to Mary held in British archives." What is important is the pattern of Mary's various sets of codes.
(4)
(a) timeline of Babington Plot:
(i) "On 6 July, 1986, Anthony Babington wrote to Mary Stuart": en.wikipedia.org for "Anthony Babington."
(ii) "On 7 July 1586, the only Babington letter that was sent to Mary was decoded by [Thomas] Phelippes. Mary responded in code on 17 July 1586 * * * This letter [from Babington] was received by Mary on 14 July 1586 * * * John Ballard was arrested on 4 August 1586": en.wikipedia.org for "Babington Plot."
(b) It is clear that Phelippes could quickly decode Babington's coded letter and Mary's in that plot, and that neither had been aware of that fact.
(c) An analogy Allies' success during (and before) World War II. See
(i) World War II cryptography
https://en.wikipedia.org/wiki/World_War_II_cryptography
(ii) Magic (cryptography)
https://en.wikipedia.org/wiki/Magic_(cryptography)
(section 9 Other Japanese ciphers: "Japanese Fleet Code (an encoded cypher), called JN-25 [standing for 'the 25th Japanese Navy system identified'] by US Navy cryptanalysts")

(5) My conclusion:
(a) Besides the newly found letters, this Cryptologia rediscovered the coded system (but not keys themselves) what Phelippes had already known.
(b) I wish to remind you of
this paper at page 102: "To our great surprise, those letters turned out to be from Mary Stuart, from 1578 to 1584, addressed mostly to Michel de Castelnau, seigneur de La Mauvissière, the French ambassador in London between 1575 and 1585. We also found in British Archives plaintext copies of seven of those deciphered letters, from 1583 to 1584, which were apparently leaked to Francis Walsingham,Footnote3 Queen Elizabeth I’s secretary and spymaster, by a mole in Castelnau's embassy.[Footnote4] Those plaintext copies allowed us to definitively confirm the origin of the deciphered letters."

(c) Thus this paper is much like rediscovery of Gregor Mendel's works. See Gregor Mendel
https://en.wikipedia.org/wiki/Gregor_Mendel
(By 1900 "independent duplication of his [Mendel's] work by Hugo de Vries and Carl Correns and the rediscovery of Mendel's writings and laws")
