What is amuse? How milton's muse different from.classial epic muse?

When used a verb, to muse is to consider something thoughtfully. As a noun, it means a person — especially a woman — who is a source of artistic inspiration. In mythology, the Muses were nine goddesses who symbolized the arts and sciences. In the prologue of Paradise Lost, Milton invokes Urania, referring to her as the "Heav'nly Muse". The choice of Urania as a muse differs from the muses used by classical poets of the time.
