the strongest
imagery in “Fast
rode the knight”
by Stephen
Crane (1905).
Peer Instruction Questions
Peter Newbury (UCSD)
Fast rode the knight
With spurs, hot and reeking,
Ever waving an eager sword,
"To save my lady!"
Fast rode the knight,
And leaped from saddle to war.
Men of steel flickered and gleamed
Like riot of silver lights,
And the gold of the knight's good banner
Still waved on a castle wall.
. . . . .
A horse,
Blowing, staggering, bloody thing,
Forgotten at foot of castle wall.
A horse
Dead at foot of castle wall.
