Christina Rosetti might have had Hamlet in mind when she wrote The Bourne. The Danish Prince, in one famous soliloquay, speaks of "the undiscovered country from whose bourn/no traveller returns." As keen as he was at dispatching Claudius, Hamlet had much time, possibly too much, to reflect upon his condition. Rosetti would surely have known the play and most likely seen it though as for that, she may have come across the title quite by accident.

Underneath the growing grass,

Underneath the living flowers,

Deeper than the sound of showers:

There we shall not count the hours

By the shadows as they pass.

Youth and health will be but vain,

Beauty reckoned of no worth:

There a very little girth

Can hold round what once the earth

Seemed too narrow to contain.

Introspective, maudlin, think you? Rosetti appeals to me for the very reason she may repel others. Reflecting on the levelling effect of death, where wealth, beauty, fame or achievement are rendered meaningless, is a passtime for deeper thought, but one that finds little purchase today. Rosetti was a devout Christian and so would have known that bodily death was but a transitional phase. This didn't stop her dwelling upon it, which she often does in her verse. If you can think with fearless clarity about what is to come, then your present may also become clearer too.
