Famous quotes containing the words magic and/or number:
“Mistress, there are portents abroad of magic and might,
And things that are yet to be done. Open the door!”
—Elizabeth Jane Coatsworth (b. 1893)
“At thirty years a woman asks her lover to give her back the esteem she has forfeited for his sake; she lives only for him, her thoughts are full of his future, he must have a great career, she bids him make it glorious; she can obey, entreat, command, humble herself, or rise in pride; times without number she brings comfort when a young girl can only make moan.”
—Honoré De Balzac (1799–1850)
