The Borg Cipher

A deciphered book written in the 17th century about how to treat symptoms and diseases. A glass of red wine of high quality was part in many, albeit oftentimes bizarre, and rather painful treatments.

The Borg cipher is a 408 pages hand-written manuscript, probably from the 17th century. The manuscript is located at the Biblioteca Apostolica Vaticana and called MSS-Borg.lat.898.

The cipher was decoded by Nada ALdarrab, Kevin Knight and Beáta Megyesi.

The cipher consists of 34 different characters, comprising of graphic signs and Roman letters, combined with some diacritics. Catchwords used for page numbering are often written at the bottom of left–hand pages. The entire manuscript is encoded with the exception of the first and last two pages, and some headings in Latin in the first part of the manuscript. 

The book is transcribed and deciphered and brought to light a text in Latin (and partly Italian) describing how to treat various kinds of symptoms and diseases and reveals other pharmaceptic knowledge or secrets of that time. 

Part of the DECODE project

The decipherment of the Borg cipher was part of the DECODE project aiming at the collection and decipherment of historical ciphers in early modern times in Europe.
