It's refreshing to walk into an exhibition and discover a diversity of works by one artist, rather than a collection which appear to be just reworks of the same theme. The 41 mixed-media and acrylic paintings in Jon Rowland's show in the gallery at Oxford's Said Business School are, as the title suggests, about Places+Spaces+Life.

Let's start with those that come under the Life umbrella. They are certainly worth talking about, if only because these colourful, thought-provoking nudes come to life through the simplest of lines. Many appear to be taking the art of relaxation just as far as it can go, with slack arms and legs protruding from a twisted body.The woman depicted in Still Life Studio 5 (pictured) appears to be relaxing comfortably, however. Thick lines of mustard yellow (a colour that Jon Rowland uses frequently) enhance the shape of her body as she leans back against a bright red background. Other nudes have been given mustard yellow flesh tones. Some show just a knee and an arm and one or two are highlighted in black. Then there's the male torso Hunk Hunk, which as the title suggests, is a real hunk of a man, caught off guard and moving away from the viewer. He's been given the red brush treatment, leaving us to guess whether he's sunburnt, or just blushing. It's certainly a bold and very masculine piece.

The themes of Jon Rowland's landscapes and cityscapes have emerged from his travels to Venice, Scotland, France and Andalucia and, as with his nudes, are abstract yet, in some cases, identifiable. Three depict Foxcombe Wood - The Pond, but in quite different guises, with green upon green suggesting trees and wild, almost frantic, brushstrokes of creamy white signifying with great effect the presence of water. Then there's Venetian Glimpse, a superb if somewhat tantalising study, which invites the viewer to look through a leaded window to the obscured city beyond.

This exhibition continues at the Said Business School until December 31 and is open to view from Monday to Saturday from 10am to 4pm and Sunday by special arrangement.
