What does thou art the ruins of noblest man?

"Thou art the ruins of the noblest man" is a quote from William Shakespeare's play Hamlet. In the play, the character Hamlet is contemplating the skull of a jester, Yorick. He reflects on how this once-vibrant man has now been reduced to nothing more than a pile of bones. Hamlet is struck by the transience of life and the inevitability of death. He realizes that even the most powerful and influential people will eventually come to the same end. This quote is a reminder that no matter how great or noble we may be, we are all mortal and will eventually perish.
