Famous quotes containing the words magic and/or number:
“Thou treacherous, base deserter of my flame,
False to my passion, fatal to my fame,
Through what mistaken magic dost thou prove
So true to lewdness, so untrue to love?”

“Among a hundred windows shining
dully in the vast side
of greater-than-palace number such-and-such
one burns
these several years, each night
as if the room within were aflame.”
