The case record
What was reported?
The Voynich Manuscript contains an unidentified script and elaborate illustrations. The physical book is medieval, but no complete reading has gained broad scholarly acceptance.
Wilfrid Voynich brought the manuscript to modern scholarly attention in 1912. Its drawings suggest botanical, astronomical, bathing and pharmaceutical sections, although labels such as recipe or medical text remain interpretive. Yale’s Beinecke Library now holds the volume as manuscript 408.
Sortable date is modern rediscovery, not manufacture; the manuscript’s material age is broadly fifteenth century. Marker identifies its present repository, not its uncertain place of origin.

Evidence in the record
The manuscript itself, digitised images, ownership history and material testing can be examined independently of proposed decipherments. The library notes consistency with fifteenth-century materials while its descriptive dating also preserves later possibilities.
Competing explanations
Official and research context
Yale’s collection description and scholarly publication present the manuscript as undeciphered; no proposed reading is treated as accepted.
Conventional explanations
A natural language in an unfamiliar writing system, a cipher, an artificial system or pseudo-writing have all been proposed. Repeated patterns can support structural analysis without demonstrating meaning. A proposed reading must work consistently across the text and fit historical constraints.
Arguments that remain contested
The author, language or encoding process and intended meaning remain unknown.
