Don Juan, Canto 1.
What a strange thing is man! and what a stranger
Is woman? what a whirlwind is her head,
And what a whirlpool full of depth and danger
Is all the rest about her! whether wed,
Or widow, maid, or mother, she can change her
Mind like the wind; whatever she has said
Or done, is light to what she'll say or do;—
The oldest thing on record, and yet new!
Don Juan, Canto 9.
