Modus II: from printed letters to German

Follow one worked example from the printed page through transcription and extraction to a mechanically recomputed plaintext. Every visual has an equivalent table or prose account.

1. Printed example

Crop of printed page 251 containing the Modus II alphabet, intention, significant letters, and example
The crop preserves the Alphabetum, Intentio, Literae significantes, and Exemplum secundi on printed page 251.

Printed evidence

Intentio: Ich bittedich komm von stund an zu mir es thut sehr noth

English: I beg you, come to me at once; it is very urgent.

Open the containing work (segment alignment; The stable passage index identifies the printed Intentio within this containing source segment.)

2. Transcribe and extract

Transcription / repair OCR-preserving sample of the Latin Exemplum. After the initial printed marker, alternate words are significant; their initials are read in order. OCR errors remain unresolved, so this sample demonstrates the extraction rule but is not silently forced to agree with the separately printed cipher line.

C Reator genyri humani apice Deus famelis suor Zelo rellitudine gu berna quatenus bene conueniant sancti celestiumus praemium gaudium exultium

Initials from the bold alternate words: gafzgqccg

Inferred operation For the cover, take the initial of every alternate significant word after the marker. For the separately printed Literae significantes, read each period-separated letter from left to right and remove separators without reordering.

Human/vision reading of the printed, period-separated letter line; periods are editorially represented as separators.

3. Invert the printed Alphabetum

Printed evidence Each first letter is plaintext; each second letter is its printed cipher substitute.

Inferred operation Invert the printed plaintext-to-cipher Alphabetum and substitute one letter at a time.

4. Read the computed result

Computed from the committed transcription:

ichaiderichkomvonstvldznyvvmitisdvgsgxroit

Printed Intentio, normalized to the same 24-letter alphabet:

ichbittedichkommvonstvndanzvmiresthvtsehrnoth

The difference is evidence about the transcription, not a failed cipher rule. The edition displays both strings so readers can test alternative letter readings against the scan.
