In 1981–82 Jonah served a year’s fellowship at Gregynog Hall, the University of Wales’s residential study centre near Newtown, Powys. He wished to spend the time developing his watercolour painting, a medium in which he had delved only intermittently for many years. The result was a substantial body of work of which Three Men on a Winter Hill is a fine example. It juxtaposes quotations from John Berryman’s lines on Brueghel’s snowy scene of hunters in his poem ‘Winter Landscape’, the first line of T.S. Eliot’s ‘The Journey of the Magi’ and Psalm 147 Verse 16 in English and Verse 17 in Welsh.
