Famous quotes containing the words king and/or frederick:
“... and the next summer she died in childbirth.
That’s all. Of course, there may be some sort of sequel but it is not known to me. In such cases instead of getting bogged down in guesswork, I repeat the words of the merry king in my favorite fairy tale: Which arrow flies for ever? The arrow that has hit its mark.”
—Vladimir Nabokov (1899–1977)
“For should your hands drop white and empty
All the toys of the world would break.”
—John Frederick Nims (b. 1913)
