Context: He did not say a monument to what, but he meant, I am sure, to leave it as a monument to the loyalty of our soldiers, who would bear all the horrors of Libby sooner than desert their flag and cause. We struggled on, the great crowd preceding us, and an equally dense crowd of blacks following on behind all so packed together that some of them frequently sang out in pain.

As quoted in &quot;Some day my plinth will come&quot; by Lynn Barber in The Guardian (27 May 2001) http://observer.guardian.co.uk/life/story/0,6903,497037,00.html

Statement accepting the Screen Actors Guild Achievement Award, read by Julia Roberts, because of Audrey's failing health. (January 1993)
Context: I am more than ever awed and overwhelmed by the monumental talents it was my great, great privilege to work for and with. There is therefore no way I can thank you for this beautiful award without thanking all of them, because it is they who helped and honed, triggered and taught, pushed and pulled, dressed and photographed — and with endless patience and kindness and gentleness, guided and nurtured a totally unknown, insecure, inexperienced, skinny broad into a marketable commodity. I am proud to have been in a business that gives pleasure, creates beauty, and awakens our conscience, arouses compassion, and perhaps most importantly, gives millions a respite from our so violent world. Thank you, Screen Actors Guild and friends, for this huge honor — and for giving me this unique opportunity to express my deepest gratitude and love to all of those who have given me a career that has brought me nothing but happiness.

Unsourced variant: Fixed fortifications are a monument to the stupidity of man. Anything built by man, can be destroyed by him.
