The Charger and the Miller 


  A CHARGER, feeling the infirmities of age, was sent to work in a
mill instead of going out to battle.  But when he was compelled
to grind instead of serving in the wars, he bewailed his change
of fortune and called to mind his former state, saying, "Ah!
Miller, I had indeed to go campaigning before, but I was barbed
from counter to tail, and a man went along to groom me; and now I
cannot understand what ailed me to prefer the mill before the
battle."  "Forbear," said the Miller to him, "harping on what was
of yore, for it is the common lot of mortals to sustain the ups
and downs of fortune."
