pieces of lead to it, the number of his years, joining them up with zinc and copper wire: Albero/filo di zinco/rame ("Tree/Wire of Zinc/Copper). He enclosed the top of a tree in a net burdened by the weight of plants: Crescendo innalzerà la rete ("Growing It Will Raise The Net). He pressed his body to a tree and marked on the trunk the points of contact with barbed wire: L'albero ricorderà il contatto ("The Tree Will Remember the Contact"). In another of Penone's earliest experiments, Continuerà a crescere tranne che in quel punto ("It Will Continue to Grow Except at that Point") (1968), he inserted a steel cast of his hand in a tree trunk, forcing the tree to grow around his hand. He immersed in a stream a tub of cement with the dimensions of his body on which he had left the imprints of his hands, feet and face: La mia altezza, la lunghezza delle mie braccia, il mio spessore in un ruscello ("My Height, the Length of My Arms, My Breadth in a Stream"). In 1969, Penone's works were published in the Germano Celant's seminal publication Arte Povera in a form of a sort of diary correlated with drawing, photographs and brief notes. Six black-and-white photos, each of which documents a different action, were exhibited at a group exhibition in the gallery of Gian Enzo Sperone in Turin in May of the same year. Other Penone works include: Pane alfabeto ("Bread Alphabet"), a large loaf of bread pecked by birds and thereby revealing the metal letters it contains; Scrive/legge/ricorda (Writes/Reads/Remembers), a steel wedge with the alphabet scored on it embedded in the trunk of a tree; Gli anni dell'albero più uno ("The Years of the Tree Plus One"); a bough covered with wax with, imprinted on it, the bark of the tree on one side and on the other the gestures of the artist; Alberi e pietre, I rami dell'albero più uno, Zona d'ombra ("Trees and Stones, The Boughs of the Tree Plus One, Shadow Zone") were all created between 1969 and 1971 in the forest of Garessio, where the artist assimilated his work to the behavior of other living things, for the most part, trees. In 1969, Penone also produced the work titled Il suo essere nel ventiduesimo anno di età in un'ora fantastica ("His Being in the Twenty-Second Year of his Age in a Fantastic
