What Is the Invocation of a Muse in the Odyssey?

In epic poetry, such as the "Odyssey," the narrator often asks the Muse for inspiration at the beginning of the work. Similar invocations occur in Vergil's "Aeneid," Dante Alighieri's "Divine Comedy" and John Milton's "Paradise Lost." In the "Odyssey," the narrator asks the Muse to tell him anything she knows about the adventures of Odysseus from whatever sources she can learn them.
