This publication documents Italian artist Giuseppe Penone's sculpture "Spazio di Luce" "Space of Light", installed at the Whitechapel Gallery in London. "Spazio di Luce" is a bronze cast of the thick layer of wax surrounding a 40-foot-tall larch, with a radiant goldleaf interior that spreads dramatically across the columned gallery. The work references and augments a 1969 work of Penone's titled "All the Years of the Tree plus One," for which he also cast a tree in wax. Created in close collaboration with the artist, this volume brings together previously unpublished drawings, photographs of historic actions and recent sculptures and a selection of the artist's own writings. It also includes an interview between Achim Borchardt-Hume and the artist and an essay by art critic and scholar Douglas Fogle focusing on Penone's work with trees, alongside color documentation of the exhibition at the Whitechapel Gallery.
