"Parole in geometria": la ricerca geometrica nel libro d'artista "Iperipotenusa" di Lia Drei

Once the Experimental p. experience lived together with Francesco Guerrieri was over, in 1970 a new season opened up for Lia Drei that went beyond the limits of painting, dedicated to the realisation of happenings and installations of coloured geometric structures. These works can be included in the terms of environmental art: an artistic investigation more open to sociality and direct confrontation with the public, which was anticipated by Lia Drei in 1969 by a particular and unprecedented project in her research, the book object Hyperhypotenusa. Due to the significance of this shift from painting on canvas to the environment, this book constitutes an important moment in the painter's artistic process. It is the first in a series entitled "Quadrilogy of the Rectangle Triangle", which stems from the assemblage and re-elaboration of several collages that Drei makes with shaped coloured paper.
