Meanwhile Satan alights upon the bare convex of this World’s outermost orb; where wandering he first finds a place since called the Limbo of Vanity; what persons and things fly up thither: thence comes to the gate of Heaven, described ascending by stairs, and the waters above the firmament that flow about it. His passage thence to the orb of the Sun: he finds there Uriel, the regent of that orb, but first changes himself into the shape of a meaner Angel, and pretending a zealous desire to behold the new Creation, and Man whom God had placed here, inquires of him the place of his habitation, and is directed: alights first on Mount Niphates.
