No man is an island,
entire unto itself,
girt by the sea.
Send not to know,
for whom the bell tolls,
it tolls for thee.
This is from memory and may not be exact.

That is from John Donne, I also like Milton:
A dungeon horrible, on all sides round,
as one great furnace flamed
but from those flames, no light,
but rather darkness visible,
served only to discover
sights of woe, regions of sorrow
where peace and rest can never dwell
but torture still urges
and a fiery deluge fed
with ever burning sulphur, unconsumed.
Your turn?
