Giuseppe Penone (Italian, born 1947). Propagazione (Propagation) (detail). 1995–2010
This drawing, which Penone made for On Line but conceived in 1995, began with the artist’s fingerprint on a sheet of paper. The pencil and ink lines, following those created by the inked ridges of skin, radiate outward, filling the paper then spilling over onto the walls of the gallery space, like the rings of a steadily growing tree.
