 The common nightingale is an important symbol for poets from a variety of ages, and has taken on a number of symbolic connotations.Homer evokes the nightingale in the "Odyssey", suggesting the myth of Philomela and Procne (one of whom, depending on the myth's version, is turned into a nightingale).This myth is the focus of Sophocles' tragedy, "Tereus", of which only fragments remain.
