After taking this picture, I had a vague thought "for whom the bell tolls". Later realized what had struck me was the memory of the title of an old novel by Ernest Hemingway. Trying to look it up, I found the title was taken from John Donne's Meditation 17 Devotions Upon Emergent Occasions and came across these beautiful lines.
No man is an island,
Entire of itself.
Each is a piece of the continent,
A part of the main.
If a clod be washed away by the sea,
Europe is the less.
As well as if a promontory were.
As well as if a manor of thine own
Or of thine friend's were.
Each man's death diminishes me,
For I am involved in mankind.
Therefore, send not to know
For whom the bell tolls,
It tolls for thee.
