Why did the speaker provoke the muse in Paradise Lost?

The speaker, John Milton, invokes the muse at the beginning of Paradise Lost to seek divine inspiration and guidance in his epic poem about the fall of mankind and the battle between good and evil. By invoking the muse, Milton is asking for divine assistance in telling the story accurately and with the appropriate depth and understanding. It also sets the tone for the epic nature of the poem and acknowledges the tradition of epic poetry.
