"The art of the poet is to explore the very questions of human existence". The art of poetry is a deep and involved process, which when used properly to infer an existentialist message, can turn lines of ink into a work of art. Major and famous authors of times past and present have frequently, and continue to deal with these issues of human existence. Two of these masters, William Shakespeare and Robert Frost are examples of writers who have made the step from poetry to works of art. This is shown in Frost’s On a Tree Fallen Across the Road and in Shakespeare’s Sonnet No.
