"As to imitation, poetry is a mimetic art. It creates, but it creates by combination and representation. Poetical abstractions are beautiful and new, not because the portions of which they are composed had no previous existence in the mind of man or in Nature, but because the whole produced by their combination has some intelligible and beautiful analogy with those sources of emotion and thought and with the contemporary condition of them."
— - Percy Bysshe Shelley, Author’s Preface, Prometheus Unbound
