Gilberto Zorio is rightly included among the greatest representatives of the Italian Arte Povera. He works in the field of process art and is interested in the energy of materials (in this case, leather) and thought (psyche and immateriality); as an example, a graphic token -such as the word "hate"- is enough to activate a short-circuit of violent and aggressive tension. In the figures and the tensions of Gilberto Zorio one can see the intimate relationship between the nature of dynamic phenomena and imaginary attributes. The effectiveness to narrate the darkness of man is, in this work, quite clear: the word "hate" is branded on the skin of an ox in such a way that the violence of the gesture is imprinted on the mind of the viewer.
