Delicate and poised, spidery and animated, these bronze casts of tree trunks, hollowed out and painted with a radiant gold-leaf interior, seem to prowl the gallery on their spindly branched limbs. This new site-specific work for the Bloomberg Commission, Spazio di Luce (Space of Light) (2012), was created by the youngest artist to have been admitted to the Arte Povera group, Giuseppe Penone (b1947), using the time-old technique of Lost Wax casting, deliberately reversing the interior and exterior of the trees.
