From the Royal Academy of Arts magazine:
On Good Friday this year, in the company of a small group of travellers, I went to visit a warehouse on an industrial estate in Bridlington, East Yorkshire. The object of our pilgrimage was not this nondescript structure but the painting that it briefly sheltered. There, on the far wall, hung the largest picture that David Hockney RA has ever created – perhaps the most sizeable ever to be painted in the open air. This was a first for the artist, who had never before seen his entire work assembled together.
The subject of the Big Picture is one of several spots in the landscape west of Bridlington where he has been working. It consists principally of an immense net of interconnecting twigs and branches. That is what Hockney was gazing at so hard, as he contends it is only by looking very long and hard that you begin to understand what you are seeing. ‘A picture this size just has to be of certain kinds of subject. Nature is one, because there is an infinity there that we all feel.’
