Who does John Milton call on in the fall of Satan?

In "Paradise Lost," John Milton calls upon the Muse, specifically invoking the "Heav’nly Muse," to inspire him in recounting the epic tale of Satan's fall from grace. This invocation serves to emphasize the divine nature of his subject matter and to seek guidance in articulating the complexities of good and evil. Milton's appeal to the Muse sets the tone for the exploration of themes related to rebellion, sin, and redemption throughout the poem.
