From the reviews: "The book under review is basically a translation of de Witt's second volume, which, in turn, provides additional insights on Descartes' ideas. ... My overall opinion is that this book surpasses D. E. Smith's translation of Descartes' La Geometrie ... . this helps the reader to gain real insight into the mathematics of the 17th century, and the editors must therefore be congratulated on the production of a text that should be included in every university library ... ." (Peter Ruane, The Mathematical Association of America, March, 2011) "Like in the 2000 edition of the first book of Jan de Witt's Elementa curvarum, each page of the original is represented by a facsimile preceded by its English translation. ... A historical introduction provides the context of Elementa curvarum; the appendix starts with the background of Pappus's problem and ends with its solution for five lines by Descartes. The volume offers ... a carefully prepared English edition of a source, which presumably had considerable impact on the subsequent development of the subject."
