Gregory Corso's poem "Marriage," is very profound.
It is also very appropriate to mark the grave of
Percy Bysshe Shelley. Shelley was a poet of very
extraordinary sensitivity, who wrote poignant and
magnificent poetry.

Here is an Excerpt:

"When night advances through the sky with slow and
solumn thread,
The queenly moon looks down on life below as if she
read
Man's soul, and in her scornful silence said
All beautiful and happiest things are dead!"
