Analysis of In Time Of

I
Only a man harrowing clods
In a slow silent walk
With an old horse that stumbles and nods
Half asleep as they stalk.

From the heaps of couch-grass;
Yet this will go onwards the same
Though Dynasties pass.

Yonder a maid and her wight
Go whispering by:
War's annals will cloud into night
Ere their story die.
