Part 12 - Training in this Art
1. Here we deal with training in this Art in three parts: the first comprises the 13 parts in which this Art is divided. The artist in this Art must be thoroughly familiar with them and know how to apply questions to loci appropriate to the conditions of each question's subject matter.
2. Secondly, the artist must be skilled in applying the technical procedure of this Art and using the methods of proof provided in the text so he can prove the solutions to peregrine questions, as one example exemplifies and clarifies another.
3. Third, the artist must be skilled in the method of applying questions and solutions to one and the same conclusion, as shown in the third and fourth figures. And this is enough about training, for the sake of brevity.
