Writing an analytical essay about art is quite similar to writing one about literature. If you want to construct a strong analytical thesis statement about art, you will want to be very clear with yourself about precisely what your argument is. Try stating it mentally in your own words before you commit it to writing. Then, define the subject of your writing clearly and construct a statement that depicts precisely what you hope to show about this subject. Throughout your essay, you will be looking to the art itself to provide evidence that supports your underlying analysis.
