In the field of social objects, in the hierarchy of values (and often of prices) a special place is occupied by those inscriptions that should move us or amuse us, frighten us or make us think, or even just make us look good into society: that is, the works of art. The artwork begins to exist only when we have an expression and an inscription. This teaches us — and Ugo Nespolo knows it better than anyone else — how important the work (understood as labour) is in art: craft is the father of all arts, and, in the end, it is true that genius is first of all diligence.
