This paper will explorePtolemy?s definitions of the sciences in the introduction to theAlmagest and analyze how and whether, in the rest of his corpus,Ptolemy portrays mathematics yielding accurate results in its owndomain as well as when applied to physics.Les Grandes conférences sont organisées par :* Archives Henri Poincaré (UMR 7117)* Département de Philosophie de l'Université Nancy 2* Colloque permanent transfrontalier Nancy-Saarbrücken* MSH Lorraine (USR 3261)Le programme mis à jour :http://poincare.univ-nancy2.fr/Activites/?contentId=5293
