At the Castello di Rivola, Turin, it is currently possible to see a celebration of Arte Povera well before it reaches Tate Modern in just over two months time. Entitled Zero to Infinity: Arte Povera l962l972, this exhibition has all the makings of a historical retrospective. The stars of the movement include Kounnellis, Gilardi, Pascali, Boetti, Pistoletto, Calzolari, Pernone, Mario Merz, Zorio, and Paolini. Meanwhile, Giovanni Anselmo is showing an installation at the Villa Medici, Rome, entitled Il panorama verso oltremare dove le stelle si Avvicinano di una spanna in piu mentre il colore solleva la pietra (through 28 May). It remains to be seen whether the installation of Arte Povera at Tate Modern can again encapsulate the essential vitality and diversity of the original movement, having all things in its favour where space is concerned. Watch this space.
