Nella Cavallerizza di Palazzo Butera, è esposto un dipinto di Tom Phillips, Berlin Wall with German Grass and Skyes, II, del 1973. Si tratta di un quadro politico: il Muro di Berlino esisteva da dodici anni, ma all'epoca non circolavano immagini della barricata che divideva la città. Le cartoline tedesche di allora, sia ad Est che ad Ovest, mostravano invece prati e cieli azzurri. "The day after I got married the East Germans built a wall through Berlin, using pre-cast concrete slabs that were to have been the sides of workers' flats. I first saw the wall in 1971, ten years later, and went specially again to see it last December before starting work on the pictures. No popularly available images exist of the East German side and my painting therefore only shows fragments of the structure seen from the West (as is after all appropriate): the other side is not in any case 'The Berlin Wall' but 'the anti-fascist defensive wall' (now more warmly described as 'the state frontier of the DDR in Berlin'). Grass and sky however occur freely on postcards produced both in West and East Germany. Some places have associations: e.g. one of the sections shows grass from Goethe's garden brought from East Germany, in postcard form, by my wife). [..]. Apart from obvious ironies I am not quite sure how the picture now relates to the wall, its source. It certainly represents the way I see and understand that phenomenon." Tom Phillips.
