Who wrote the lines of poetry "quoted" by Lincoln at the Soldiers' Home?

[Steve Whitlock]

Is it possible that Lincoln himself became the anonymous poet in that moment, in that place, in the fall of 1864?

David, what you propose as a possibility will be my guess as to the answer to your trivia question. I will guess Lincoln himself.

It is possible that Mr. Lincoln wrote the lines in question; however, not all books have been digitized, so there may be a lesser known author who wrote the lines that inspired Mr.Lincoln. I tried finding a poem that I know was in a book, and nothing comes up, so it remains uncertain, but possible, that Abraham wrote the lines.
