Apollonius de Perga or Perge (v. 262 - v. 190 av. J. - C.) was a Greek geometrician and a Astronome, famous for his writings on the conic sections. It was Apollonius which gave to the ellipse, with the Parabole, and the hyperbole the names that we know to them. The assumptions of the Orbit S eccentrics, to explain the apparent movement of planets and the variation speed of the the Moon, are also allotted to him.

The Stoical of conical the , under its original version in Greek, is a whole of eight major works of the ancient geometry which had in Apollonius. The first four books reached us in Greek, with the comments of Eutocius. The books five to seven reached us in a translation in Arab language by Thâbit-ibn-Qurra, and re-examined by Nâsir-AD-Dinet and eighth disappeared. The whole of this work, with a restitution of the eighth book, was published (Greek text and Latin translation), by Edmund Halley in 1710. This one has, moreover, translates of Arabic into 1706 two other works of Apollonius: Of section rations .

Pappus gave indications on a series of lost works which allowed the deduction of their contents by the geometricians of the Renaissance: Of spatii sections , Of sections determinata ( Of the contacts , Of the places plans). Its innovating methodology and its terminology, especially in the field of the conical ones, with influenced several posterior mathematicians of which Ptolémée, Kepler, Isaac Newton and Rene Descartes. Pierre de Fermat made in 1636 of it a restitution of the treaty De Locis plani based on the work of Pappus. Later, Gaspard Monge and Girard Desargues will use the importance of the projective reasoning to apply it to the whole of the Géométrie.
