Famous quotes containing the word arrow:

    “... 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)
