What does Hamlet say about Yorick?
As if Hamlet were not obsessed enough with death, his uncovering of the skull of Yorick, the court jester from his youth, really sets him off on a contemplation of mortality. Upon unearthing the skull in act V, scene 1, Hamlet recalls fond memories of Yorick. He recalls the many jokes that Yorick was full of and how the jester used to carry him around on his shoulders in play.
Upon gazing at the skull, Hamlet's thoughts turn more existential. He asks the skull what happened to its former jokes and songs. Yorick was a person "of infinite jest, of most excellent fancy," but now he is just dusty bones.
Ever the one to brood, Hamlet compares the fate of Yorick to that of Alexander the Great. Despite the vastly different lives and accomplishments of the two, their fate is the same: to die "and returneth to dust." It seems that here, while contemplating what has become of the once merry jester, Hamlet truly accepts that he too will meet the same end, as all people do. After this scene, Hamlet appears to have accepted his own mortality.
