Why is it sometimes effective to refer to a known myth or work of art in the title of a literary work?

An allusion is a reference within a work. You can use an allusion to achieve a well-rounded feel to your essay. You can reference to a lot of other works to give your essay a more complex meaning. Making connotations to other things such as art of mythology can strengthen the point you are trying to get across. Also, using allusion may also provoke your reader to do research on a reference you are making, which gives your essay more depth.
