The Evil Under the Sun

How long, oh Lord?
Revelation 6:10.

John Evangelist alone In Patmos
St. John the Evangelist was banished to the Isle of Patmos, where he wrote the Book of Revelation. This line might echo Robert Burns's "The Cotter's Saturday Night":
How he, who lone in Patmos banished
Saw in the sun a mighty angel stand,
And heard great Bab'lon's doom pronounced by Heaven's command.
