Here is a note on "Encryption":
One could assume that the "encryption" in Alderottis De virtutibus aquae vitae, if there was one, was similar to that in Mappae clavicula.
Quote:The Mappae Clavicula (more or less “The Little Key of the Map”, but the title and its meaning are uncertain) is a medieval Latin text which contains recipes describing crafts techniques about metals, glass, mosaics, and dyes and tints for materials. The core was probably originally compiled around AD 600, perhaps in Alexandria in Egypt. The number of recipes was expanded over the course of the centuries, and some medieval copies have deletions as well as additions, so it is better thought of as a family of texts with a largely common core, not a single text. It was one of the few scientific treatises available in the Early Middle Ages in Latin Europe. Only the twelfth century and later versions contain the recipe for the preparation of alcohol in the form of a cryptogram. There exist slightly different versions of the cryptogram in different manuscripts, here is one of them:
“De commistione puri et fortissimi XKNK cum III QBSUF TBMKT cocta in ejus necocii vasis fit aqua, quae accensam flammam incombustam servat”
That, more or less, means:
“A mixture of pure and very strong XKNK with III QBSUF TBMKT cooked in the usual vessel make a water, which will flame up when set on fire but leave the material unburnt”
The three nonsense words are simple word puzzles with a mistake. They are formed by substituting for the proper letter - in Latin - the one which follows it in the alphabet: XKNK = VINI (wines); QBSUF = PARTE (part); and TBMKT = SALIS (salt). The ‘n’ in the word XKNK is probably a mistake of the amanuenses, it should have been an ‘o’.
It is interesting to notice how, in this first description of wine distillation, the name given to the new substance thus produced, which we call alcohol, is aqua, that is, water.
