So Marius looked, methinks, and Cromwell so,
Not in the purple born, to those they led
Nearer for that and costlier to the foe,
New           of old forms, by nature bred
The exhaustless life of manhood's seeds to show,
Let but the ploughshare of portentous times
Strike deep enough to reach them where they lie;
Despair and danger are their fostering climes,
And their best sun bursts from a stormy sky:
He was our man of men, nor would abate
The utmost due manhood could claim of fate.
