The exhibition of David Gentleman's paintings, called 'On Location' and featuring his work over fifty years, closed yesterday so it can only be viewed online here. This week on the Post, as a way of narrowing the collection down – because all the paintings are so wonderful it's impossible to highlight one over another – we shall focus on Italy, partly because most of us have not been to Italy, or in fact anywhere, for nearly two years, indeed the thought of going casually there is still an impossible dream. This is the Forum in Rome, painted in 1996.
