What did you study in Greek schools?

The most important subjects in the Greek school were philosophy, rhetoric (aka oratory), and theater. Theatrical work also meant the study of literary works, along with all the myths. Philosophy included all the basic sciences. Much later, it was divided into separate sciences, and then included the entire volume of knowledge about the world order, about numbers and figures. In view of the fact that there was still not very much pure knowledge about the world, and therefore it was required to operate with abstract concepts, first drawing a theoretical picture of the world.
