Voynich Manuscript — Beinecke MS 408
Yale’s undeciphered illustrated codex: the library dates it to the late 15th or 16th century and does not endorse decipherment claims.

Yale’s Beinecke Library holds Beinecke MS 408 — the Voynich Manuscript — an illustrated codex in an undeciphered script. The library dates it to Central Europe at the end of the fifteenth century or during the sixteenth, and says scientific testing shows its materials are consistent with fifteenth-century manuscripts. It does not evaluate or endorse decipherment announcements.
Open script, closed hype
Status open on linguistic meaning; custody and imaging are cited. Pair with the Cardiff Giant the same week for a classroom contrast: cipher-in-custody versus known carved hoax.

New codicology, not a decipherment. In “Singulion Structure and the Voynich Manuscript” (Digital Medievalist, reported 6 Oct 2026), Colin Layfield (University of Malta) and Lisa Fagin Davis propose that the folded sheets were first kept as a loose stack of single bifolia (“singulions”) and were later bound in the usual nested quires, probably in the mid-to-late 15th century, which would scramble the reading order. Their case rests on a Latent Semantic Analysis of how closely the text on separated pages matches, and on drawings of streams and pipes that run into the gutter and only join up once the sheets are re-stacked. The paper doesn't read the script. Davis links it to palaeographic work suggesting up to five scribes, and floats a reading of the book as communal women's folk knowledge, while saying herself that “you cannot prove that yet.” A separate paper points the other way: Torsten Timm, in Cryptologia (online 7 Sep 2026), argues that the text's gradual drift in vocabulary fits his self-citation hypothesis, under which the text need not carry linguistic meaning. Status stays open.
