PONCELET, Jean-Victor. Traité des propriétés projectives des figures; ouvrage utile à qui s'occupent des applications de la géométrie descriptive et d'opérations géométriques sur le terrain.
Paris: Bachelier, 1822. First edition.

"Poncelet’s book is the source of the launch of the modern study of projective geometry, after the work of various 17th-century authors had not generated sufficient momentum to sustain the subject through the 18th century. He produced a new way of thinking about plane figures that emphasised the properties they have in common with their shadows and played down their metrical properties. He claimed to find many remarkable transformations between figures that enabled complicated figures to be simplified and geometry to work at a new level of generality." "This work contained many extremely important innovations, ideas, methods, and original results, and it played a decisive role in the development of projective geometry in the nineteenth century" (DSB).
