Louis XIV's great arc
587 numbers hidden syllable
Hundreds of numbers were written instead of words in the French royal family's secret document. The Great Arm Lake, created by the Rossignol family, became a document that could not be read even within the National Archives after its use was cut off.
Daeamho was a combination of syllables, words, names, and nuns. The reason why Bazri's decoding is convincing is not because he made a single sentence, but because the same numerical response was repeated in several documents.
Prologue: Recorded Night
After the night deepens, the data was spread on the desk. The first thing that caught my eye was not the answer, but the imbalance. Some scenes were as clear as photographs and some time zones were empty as a whole. People try to capture one clear scene and explain the whole thing, but I marked the empty section first. Mysteries arise because there are many clues, but they also arise because the distance between clues is too far.
At the end of the 19th century, Etienne Bazri analyzed the frequency and repetition of numbers over the years. The biggest shift was to discover that a single number represents not a single letter but a French syllable, word, and meaningless sign.
I deliberately read the famous hypothesis at the end. First of all, when we encounter the conclusion, it seems that all objects and symbols exist for that conclusion. Therefore, the timetable, place, object, and original text were organized first, and the witness and interpretation were placed in different compartments. The novel-like atmosphere was drawn from the cold texture of the actual record, not from a made-up secret.

Although the cryptographic system has been decoded, historical figures and event interpretations of some documents continue to require comparison of historical records.
'Unexplained' is not the same as 'supernatural', 'a huge conspiracy', and 'only this hypothesis is possible'. I didn't count the blanks as evidence.
Scene Reconstruction: Finally, the place of the certain point
was changed to the actual movement, not the stage in your head. We divided the starting point, the last check point, and the location where the item was found and calculated the minimum time required in between. When the dramatic description of later generations was removed, small and specific elements such as sound and lighting, doors and roads, paper and ink, and the spacing of symbols came forward.
The person's mind was not fixed and the action was written first. The same behavior can be caused by fear, planning, error, and fatigue. If it is a code, the same symbol can be a sound, a word, a separator, and a meaningless sign. After writing down all possible roles, he erased the roles that conflict with other records one by one.
Clue 1. Daeamho is a numerical naming code created by the Rossignol family for the French royal family.
I split this sentence into three pieces first. It indicated who first checked, how close the confirmation was to the incident, and where the later interpretation was attached. Old events and codes turn into clearer stories than the original while being repeatedly cited. But clarity is not the same thing as accuracy. In my notes, I separated the direct record, the traces left by the object, and the reasoning of later generations into different colors.
This clue was then matched with the record, "There were about 587 numerical items in the codebook." It is not a good hypothesis if one hypothesis explains only the first sentence and avoids the second sentence. In particular, if you fail to pass the question, "How can you notice why the character frequency analysis failed?" the attractive explanation also lowered the score. I've seen clues that make the conclusion uncomfortable longer than clues that make the conclusion cool.
If you look at the clues this way, the case seems a little less dramatic. Instead, there is a boundary between how far it is clear and where it is imagined. That boundary is necessary to correct reasoning when new data are released. The most dangerous moment in the unwritten record is not when you make a false hypothesis, but when you turn the hypothesis into a sentence of fact.

Put three hypotheses on the same scale The
hypothesis was not evaluated as a cool sentence. The number of clues to be explained, the number of newly requested assumptions, and the degree to which they endure the opposite evidence were written, respectively. Even if one clue is fully explained, it is not a good hypothesis if the other records have to be discarded.
Hypothesis A. often repeated syllable candidates in French correspond to numerical frequencies.
This explanation has the advantage of accepting "Daeamho is a numerical naming code created by the Rossignol family for the French royal family" as a relatively small assumption. I assumed that this hypothesis was correct and walked time and space all over again. Each time people, objects, and symbols moved to the next location, they wrote down the actions and times they needed. There must have been a hidden assumption at the point where the sentence was cut off.
The biggest weakness is that "each number could represent syllables, words, names, and meaningless signs rather than letters." If you keep adding accomplices, coincidences, and lost things to keep the hypothesis alive, you can explain anything. However, such an explanation does not predict new clues. I only scored when two independent records pointed in the same direction, and I scored every time I called in a new exception.
117100118So, whether or not to adopt this hypothesis as a conclusion was judged not by atmosphere but by cost. The number of clues to be explained, the number of newly requested households, and the degree to which they endure evidence against them are listed in the same table. Novel scenes were used to show the texture of facts, but not as evidence to fill in the blanks.
119101120Hypothesis B. A numerical sequence with a high probability of life and place names in the context is considered as a separate nomenclature.
121102122This explanation has the advantage of accepting "there were about 587 numerical items in the codebook" as a relatively small assumption. I assumed that this hypothesis was correct and walked time and space all over again. Each time people, objects, and symbols moved to the next location, they wrote down the actions and times they needed. There must have been a hidden assumption at the point where the sentence was cut off.
123103124The biggest weakness is that it does not fully explain "some of the French archival documents were not read for a long time after they were discontinued."

Novel scenes were used to show the texture of facts, but not as evidence to fill in the blanks.
127105128Hypothesis C. Remove meaningless numbers that interfere with plain text, but verify the same rules in the entire document.
129106130This explanation has the advantage of accepting "each number could represent syllables, words, names, and meaningless signs rather than letters" as a relatively small assumption.

Conclusions I abandoned
137111138When I started the investigation, I was also drawn to the most famous explanation. It organized the case into one sentence and gave intention to everything. However, in contrast to the original record, each blank required a new coincidence. I erased the conclusion then and started again. Good reasoning is not about adding anything, but about removing unnecessary assumptions.
139112140I've been holding onto a ticket that substitutes one number into one letter for a long time and kept failing. When the units were changed to French syllables, repetition created a sentence rhythm. The difficulty of the password was the wrong analytical unit than the key size.
141113142In particular, the details repeated on later articles and the Internet were separated from the source. Just because the same sentence appears in multiple places does not mean that there are multiple independent sources. We first checked the possibility that one error was duplicated. After this process, the case became less colorful, but the weight of the remaining clues increased.
Anti-evidence: Sentence to destroy my reasoning
145116146The investigation ends quickly if I gather data that upholds my conclusion. So I put the three most uncomfortable questions next to the conclusion.
147117148- How can we notice why the character frequency analysis failed? 150119151
- How to find boundaries in a code that mixes syllables and words 152120153
- What is needed to prevent the judgment of erasing the null code from flowing into arbitrary decoding?
These questions are not decorative. It is a switch that will change its conclusion when new data comes in. The ranking of the hypotheses changes immediately when directly linked information, such as the sighting source, preserved physical evidence, comparative samples from the same author, and independent dating. On the contrary, when the word "likely" increased, the ranking did not change.
Final Reasoning: I Reached
159125160Daeamho was a combination of syllables, words, names, and nuns. The reason why Bazri's decoding is convincing is not because he made a single sentence, but because the same numerical response was repeated in several documents.
This conclusion is not a complete final judgment. The direction calls for the fewest assumptions in the currently disclosed records and explains the most clues at the same time. It is also clear that what comes out changes the conclusion. Reliable original records, verifiable legal science data, and independent evidence directly linking people and objects are needed.
163127164I do not write that the case is closed. Instead, write down how far you can close it. That boundary is the result of this investigation. The fun of mystery is not that anything is possible. It's about finding out what you can throw away among the possible explanations.
Additional Survey Record 1. Redraw the timetable
167130168Re-expanding the data on the desk, this time covering the conclusion. The Great Arm Lake is a numerical naming code created by the Rossignol family for the French royal family, leaving only "the Great Arm Lake is a line of place and time." Unconfirmed sections were not filled by imagination but marked with blank squares. The larger the square, the lower the reliability of the hypothesis to pass through the section.
169131170On top of it, I posted an explanation saying, "A frequently repeated syllable candidate in French corresponds to the frequency of numbers." At first, everything seemed right, but when I substituted the question, "How can I notice why the character frequency analysis failed?" a weak connection was revealed. Hypothesis has to endure the question. If you keep making new coincidences to avoid questions, you will create, not reasoning, from that moment on.
171132172The results obtained in this section are not confirmed criminals or complete plain texts. Instead, it became clear which explanations required fewer assumptions, and what would flip the ranking if found. Even if the case is not completed, the scope of the investigation can be narrowed.
