Alphagram / anagram
Claim. Reordered letters yield a language.
Test. acyclicity + anagram baseline
Excluded: equal to the baseline (40%=40%).

The hypotheses, put to the test of chance
Here are the hypotheses on the Voynich with their honest outcome, measured against a baseline. The famous solutions are not dismissed for taste: they are taken apart with the same yardstick applied to ours. Kondrak and Hauer announced Hebrew at 80%, but the match rate equalled chance (35% vs 35% on f1r). A method that reads noise the way it reads the manuscript has deciphered nothing.

Substitution into a language
Claim. 1:1 cipher into Latin/Greek/Hebrew/Cornish/Czech/German/Slovenian/Italian.
Test. lexicon match + baseline + endings + lengths
Excluded: 0 real words at 6+ letters; = baseline.
CiphersClosed
Polyalphabetic / cryptex
Claim. Sliding key (Vigenere).
Test. conditional entropy
Excluded: it raises entropy; the Voynich is low.
CiphersClosed
Reflection (Atbash) + shift
Claim. Reversed alphabet shifted by L.
Test. entropy + endings
Does not hold: invariant or entropy increases.
CiphersClosed
Internal A/B Rosetta
Claim. Language B is A re-enciphered.
Test. 1:1 A->B remapping + baseline
Closed: no transformation; = identity.
CiphersClosed
Fillers / regular Cardan grille
Claim. Gaps filled; holes at fixed positions.
Test. position + periodicity + baseline
Unsupported: no grille; Rugg generates text WITHOUT a message.
CiphersClosed
Verbose cipher of a European language
Claim. Several glyphs = one letter.
Test. BPE: entropy vs word length
Closed: to get language-like entropy the words drop to 2-3 letters.
CiphersOpen
Verbose cipher of a monosyllabic language
Claim. An isolating Eastern language (short words).
Test. length comparison
Still open: the only technical thread to test thoroughly.
ImagesOpen
Rosettes = map
Claim. The rosettes page is topographic.
Test. morphology + literature
Shared by scholars as style/context (not an identification).
ImagesClosed
St. Peter's Square (Rome)
Claim. One rosette = the elliptical square.
Test. dating of the monuments
Excluded: colonnade 1656-67, obelisk 1586 — after the codex.
ImagesClosed
St. Mark's Square (Venice)
Claim. The center of the rosettes = St. Mark's.
Test. chronology + shape
Chronology fine, but the ring shape != a rectangular square.
ImagesOpen
Verona Arena / Colosseum
Claim. The oval ring = an amphitheater.
Test. morphological comparison
The shape holds and is period-appropriate; but the text stays mute.
ImagesClosed
Round Jerusalem
Claim. The center = the Christian holy city.
Test. cross of streets + gates
Shared schema, but the diagnostic cross of two roads is missing.
ImagesClosed
Labels = place names
Claim. The writing beside the rosettes are city names.
Test. similarity vs known toponyms + baseline
Below baseline (0.408 vs 0.406): no signal.
ImagesClosed
Zodiac labels = star names
Claim. An astronomical Rosetta stone.
Test. vs star names and lunar mansions + baseline
Below baseline (0.388 vs 0.372).
ImagesClosed
Leonardo da Vinci
Claim. The genius behind the Voynich's canals/vortices.
Test. dating + style + paleography
Excluded: born 1452; medieval drawings, not Leonardesque.
Published solutionsClosed
Kondrak & Hauer — Hebrew 80% (Alberta 2018)
Claim. Hebrew alphagram; 80% of words in the dictionary.
Test. alphagram->dictionary + baseline (f1r, Taurus)
False positive: 35%=35% (f1r), 41%=41% (Taurus). The match = chance.
Published solutionsClosed
Cheshire — proto-Romance (2019)
Claim. A mixed Romance language.
Test. glyph frequency/position
Rejected: EVA-x 547x too rare; incoherent cipher.
Published solutionsClosed
Gibbs — Latin abbreviations (2017)
Claim. A line in abbreviated Latin.
Test. philological review
Rejected by specialists.
Published solutionsClosed
Tucker/Talbert — American plants
Claim. New World flora.
