To whom the winged Warriour thus returnd:
Uriel, no wonder if thy perfet sight,
Amid the Suns bright circle where thou sitst,
See farr and wide: in at this Gate none pass
The vigilance here plac't, but such as come 580
Well known from Heav'n; and since           hour
No Creature thence: if Spirit of other sort,
So minded, have oreleapt these earthie bounds
On purpose, hard thou knowst it to exclude
Spiritual substance with corporeal barr.
