The Tate's decision to organise its collection around themes rather than around dates is academically sensible.
It is a transparent and convenient method of organising artworks and one that doesn't immediately appear too scholarly. It is, in short, a friendly approach.
And it is an idea other museums are also exploring. An exhibition called "1900", organised by the Royal Academy and shortly to open at the Guggenheim in New York, also sub-divides its content by genre: "A room of portraits", "A room of beautiful women", "A room of still lives" and so on. In putting this exhibition together, the Royal Academy was guided by the American art historian Robert Rosenblum, a man whom I understand to have championed this approach.
So the Tate is getting it right, but not so much breaking new ground as sharing good practice.
