A very important early book on distillation is Hieronymous Braunschweig's The Virtuous Book of Distillation.
It is otherwise known as the Large Book on Distillation, and it was first published in 1512, after the Small Book in 1500. I believe it was first printed in German, then translated into Dutch, then translated into English I think in 1527 but I'm not positive.
You can read some about it in Doctors and Distillers.
The full title of the book is actually: The vertuose boke of distyllacyon of the waters of all maner of herbes with the fygures of the styllatoryes, fyrst made and compyled by the thyrte yeres study and labour of the moste co[n]nynge and famous mayster of phisyke, Master Iherom bruynswyke. And now newly translate[d] out of Duyche into Englysshe Nat only to the synguler helpe and profyte of the surgyens, phisycyens, and pothecaryes, but also of all maner of people, parfytely and in dewe tyme and ordre to lerne to dystyll all maner of herbes, to the profyte, cure, and remedy of all maner dysseases and infirmytees apparant and nat apparant. And ye shall vnderstande that the waters be better than the herbes, as Auicenna testefyeth in his fourthe conon saynge that all maner medicynes vsed with theyr substance, febleth and maketh aged, and weke. Cum gratia et preuilegio regali.
And as you can tell, it can be a challenge to read in this old English style and spelling.
But in preparation for my Tales of the Cocktail seminar this year, I decided to "translate" from olde English spelling into modern spelling an important section: The Virtues of Aqua Vitae.
