Technical Articles about the Voynich Manuscript

This volume contains four articles written by personnel of the National Security Agency (NSA) about the Voynich manuscript from 1965 to 1978. The first essay, by Brigadier John Tiltman, is entitled "The Voynich Manuscript: The Most Mysterious Manuscript in the World" and was presented to the Baltimore Bibliophiles in 1967. It provides a basic summary of facts about the manuscript and its provenance and adds a survey of proposed solutions, most of which it dispenses with quite quickly. I found it interesting to discover that Tiltman was first introduced to the Voynich ms. by William Friedman, founder of the NSA, in 1947 ( ) I was also intrigued that Tiltman's scholarly research into the history of medieval herbalism included consultations with leading English academics, no doubt during visits on "Five Eyes" business.The second essay, originally classifed Top Secret Umbra, is "An Application of PTAH to the Voynich Manuscript" by Mary D'Imperio - the title itself was unclassified.
