Famous quotes containing the word reef:
“Striking his former happiness against the reef of justice he has perished unwept for and unseen.”
—Aeschylus (525456 B.C.)
“As the bird trims her to the gale,
I trim myself to the storm of time,
I man the rudder, reef the sail,
Obey the voice at eve obeyed in prime:
Lowly faithful, banish fear,
Right onward drive unharmed;
The port, well worth the cruise, is near,
And every wave is charmed.”
—Ralph Waldo Emerson (18031882)
