⁂ Very scarce with rare supplement of this polemic against Girard Desargues (1591-1661), one of the greatest projective geometers of his generation. In the process of attacking Desargues, he includes literal extracts from two of his lost works on perspective and gnomonics - the first work on projective geometry of which only one copy survives. It was also the first printed reference to La Pasqualle, the mystic hexagram, published in 1640 by the sixteen year-old Pascal in a broadside of which only 2 copies are extant.
