The Whetstone of Witte contains a treatise on algebra which is generally supposed to be the first ever in the English language. The word itself appears for the first time in this book, although it is spelt algeber. In Recorde's time algebra was more often known as the cossic arte, from the Latin cosa, meaning thing, and algebraists were for many years known as cossists. The book contains the first use ever in mathematical notation of two parallel lines to mean 'equals', and it also contains the word which suposedly has the most z's in the English language - zenzizenzizenzike - which means the eighth power of a number. This terminology is now, of course, archaic.
