"Since his first drawings in his exercise books, Mangelos referred to geometry and more precisely to the scientist Pythagoras, who was allegedly the first in Ancient Greece to claim that he was a philosopher. Mangelos probably liked that Pythagoras hasn't left a single line of writing. The philosopher is for him the symbol of a rational thought allied with a moral wisdom, long before the civilization turn which converted the reason into an instrumental and domination process of man over nature."
