Mean while in utmost Longitude, where Heav'n
With Earth and Ocean meets, the setting Sun 540
Slowly descended, and with right aspect
Against the eastern Gate of Paradise
Leveld his eevning Rayes: it was a Rock
Of Alablaster, pil'd up to the Clouds,
          farr, winding with one ascent
Accessible from Earth, one entrance high;
The rest was craggie cliff, that overhung
Still as it rose, impossible to climbe.
