Works on painting and painters occupy the 750s. The problem, however, is that you can write about painting from many different angles. You can publish a biography of a painter, or the history of a particular painting, or the history of painting in general. What you can also do is track a particular object or theme throughout history in different paintings. When you track religious iconography or symbolism, the work is then classed in 755. And that’s where we are today.
