Prize exhibit at the moment is a £23 million painting of Salisbury Cathedral by John Constable, an awe inspiring work, vast in size and as crisply coloured as the day it was first painted. Photographs don’t do it justice. Three teenage schoolgirls sat in front of it for the ten minutes I was there, not saying anything, not even moving but, like me, enjoying the artwork.

Fascinating to me were Wilson’s delightfully witty portrayal of people. It’s not something you would notice unless you could stand a few feet in front of these big canvases. Sparingly placed at the edges of his landscapes are people going about their everyday business, walking, fishing, washing clothes, swimming. His painting of the town of Pembroke has a small child climbing a tree while, at the bottom of the cliff, his father tries to beckon him down. In the background there are skinny dippers discarding their clothes and swimming in the river. Even more remarkably for the time, Wilson portrays a woman breastfeeding her baby overlooking the River Arno, Italy, while her husband lies beside her tending his fishing rod (that’s not a euphemism by the way). The woman stares out of the canvas, challenging you to contemplate the intimate moment you’ve stumbled upon.
Wilson inspired John Constable and this exhibition is heralded as a once-in-a-generation gathering together of his paintings (a once-in-300-years tercentennial celebration of his birth). A marvellous opportunity. Paintings (well, the best ones) always reveal new and interesting qualities when they’re viewed ‘live’ and close up.
