Chris Rivers is a painter of sumptuously-coloured, turbulent skyscapes. The expressively- handled paint describes seething clouds, mists and vapours. Cyclones of elemental matter billow through an indeterminate void. On closer inspection however, tiny figures can be seen caught up in the maelstrom. Our perception of the paintings oscillates between the sublime vastness of nature and small-scale incidents of human jeopardy and disaster. This is in an old-master tradition of embedding memento mori, which are not at first apparent.
