The hum of either army stilly sounds,
That the fixed sentinels almost receive
The secret whispers of each other's watch;
Fire answers fire, and through their paly flames
Each battle sees the other's umbered face;
Steed threatens steed, in high and boastful neighs
Piercing the night's dull ear, and from the tents
The armourers, accomplishing the knights,
With busy hammers closing rivets up,
Give dreadful note of preparation.
-- William Shakespeare (1564-1616), King Henry V
-- Act iv, Prologue
