The reason is that the school in Paris which teaches these principles of painting is maintained by the Academy of the Fine Arts; and its example has been followed by many other European Academies of painting. So, when we speak of a picture being Academic in character, we mean that its motive and manner of painting follow the rules laid down by the schools. To repeat a word we have frequently used before, they are based on the Academic _Formula_. Previously it was the _Classic_ formula of which we spoke. This, you remember was the rule or plan for building up a formal composition, sometimes strengthened by the introduction of classic architecture and often representing some scene or story of classic legend. And it is upon this classic formula that the Academic practice is largely based. So when a modern artist paints a picture after the fashion of Raphael’s _Jurisprudence_, we can speak of its manner and motive as being Academic, Classic, or Idealistic. Sometimes, in fact, the meaning of these words is practically the same, but not always.
