Don Illán tests the dean's gratitude
A dean of Santiago asks the Toledo magician Don Illán to teach him necromancy and promises lifelong reward. Don Illán orders partridges for supper, then conjures an illusion in which the dean rises to bishop, cardinal and pope, and at each step denies Don Illán the promised favour, finally threatening him with prison. The spell breaks, the dean is back in the room with the partridges still uncooked, and he is sent away without either the teaching or the supper, having revealed that he repays benefactors with ingratitude once he no longer needs them.
