What is the author's style in Accidental Death of an Anarchist by Dario Fo?

The Maniac is a variant of a trickster figure, a character who acts mad or simple but who is actually invested with more sense than anybody around him. Tricksters fool those who are vain or who believe themselves cleverer than everybody else. Tricksters are quite often lesser societal figures tricked by those more elevated. They belong to the ranks of the common people, appearing in stories as an assertion of their worthiness in the face of an elite group's disdain and ignorance.
