   Extractions: Little is known about Girard Desargues ' personal life. His family (on both his mother's and his father's side) had been very rich for several generations and had supplied lawyers and judges to the Parlement in Paris as well as to that in Lyon (then the second most important city in France). Desargues seems to have made several extended visits to Paris in connection with a lawsuit for the recovery of a huge debt. Despite this loss, the family still owned several large houses in Lyon, a manor house (and its estate) at the nearby village of Vourles, and a small chateau surrounded by the best vineyards in the vicinity. It is thus clear that Desargues had every opportunity of acquiring a good education, could afford to buy what books he chose, and had leisure to indulge in whatever pursuits he might enjoy. In his later years, these seem to have included designing an elaborate spiral staircase, and an ingenious new form of pump, but the most important of Desargues' interests was Geometry. He invented a new, non-Greek way of doing geometry, now called 'projective' or 'modern' geometry. As a mathematician he was very good indeed: highly original and completely rigorous. He is, however, far from lucid in his mathematical style. When in Paris, Desargues became part of the mathematical circle surrounding Marin

It is thus clear that Desargues had every opportunity of acquiring a good education, could afford to buy what books he chose, and had leisure to indulge in whatever pursuits he might enjoy. In his later years, these seem to have included designing an elaborate spiral staircase, and an ingenious new form of pump, but the most important of Desargues' interests was geometry. When in Paris, Desargues became part of the mathematical circle surrounding Mersenne, including Descartes and Pascal. It was probably for this limited readership of friends that Desargues prepared his mathematical works, and had them printed. Desargues wrote on "practical" subjects such as perspective, the cutting of stones for use in building, and sundials. His writings are, however, dense in content and theoretical in their approach to the subjects concerned. There is none of the wordy and elementary step-by-step explanation which one finds in texts that are truly addressed to artisans. Desargues' most important work is the one in which he invented projective geometry. Only one copy is now known to survive. The book is short, but very dense. It begins with pencils of lines and ranges of points on a line, considers involutions of 6 points, gives a rigorous treatment of cases involving "infinite" distances, and then moves on to conics, showing that they can be discussed in terms of properties that are invariant under projection. Desargues' famous "perspective theorem" was first published in 1648 in a work on perspective by Abraham Bosse.

    Extractions: This entry contributed by Margherita Barile French mathematician, considered as the founder of projective geometry There seems not to be much reliable information on his life and work, most of what we know comes from indirect sources. Desargues used to write down his ideas in form of brief sketches, none of which was intended for publication, and many of which went lost. He made no effort to make them understandable to potential readers: he used "microscopic characters" (Poudra 1864), an exceedingly concise style, and expressed himself in a language of his own. His only extensive work, , has survived through a transcription by Philippe de la Hire , who felt compelled to add a glossary of terms. There we learn that "navel" and "burning point" mean "focus," that "roll" denotes a cylindric or conic solid, whereas two different words, "column" and "horn," are used for the cylindric and the conic surface. The conic sections themselves are referred to as "the border of a roll cut." Other manuscripts were edited by Abraham Bosse, a student of Desargues who was also a sculptor, and profited from his teacher's attention towards the applications of geometry to art and architecture. Desargues wrote treatises on perspective, sundials, on the cutting of stones, on the mechanical applications of epicycloids, and he also designed buildings. He probably contributed to the construction of the dam in La Rochelle, by order of Cardinal Richelieu, with whom he was familiar, as we are told by
