To weep because a glorious sun has set

To weep because a glorious sun has set
Which the next morn shall gild the east again;
To mourn that mighty strengths must yield to fate
Which by that force a double strength attain;
To shrink from pain without whose friendly strife
Joy could not be, to make a terror of death
Who smiling beckons us to farther life,
And is a bridge for the persistent breath;
Despair and anguish and the tragic grief
Of dry set eyes, or such disastrous tears
As rend the heart, though meant for its relief,
And all man's ghastly company of fears
Are born of folly that believes the span
Of life the limit of immortal man.
