"[I]n the year 1543... Arithmetica Integra, of Stifelius... contained several curious things, some ascribed to a much later date. He treats... fully and ably, of pregressional and figurate numbers, and in particular of the... table for constructing them and the coefficients of all powers of a binomial so often used since... and... more than a century later was , by Pascal... called the arithmetic triangle... [T]he same table was used... by Cardan and Stevin, and other writers or arithmetic. Cardan's Opus Novum de Proportionibus... quotes it, and extracts the table and its use from Stifelius's book. ...Stifelius, at fol. 35... of the same book, treats of the nature and use of logarithms, though not under the same name, but under the idea of a series of arithmeticals, adapted to a series of geometricals. He there explains all their uses; such as that the addition of them, answers to the multiplication of their geometricals; subtraction to division; multiplication of exponents, to involution; and dividing of exponents, to evolution. And he exemplifies the use of them in cases of the Rule-of-Three, and in finding mean proportionals between given terms, and such like, exactly as is done in logarithms. So that he seems to have been in the full possession of the idea of logarithms, and wanted only the necessity of troubleſome calculations to induce him to make a table of such numbers."
