Famous quotes containing the words ancient and/or times:
“It is the dissenter, the theorist, the aspirant, who is quitting this ancient domain to embark on seas of adventure, who engages our interest. Omitting then for the present all notice of the stationary class, we shall find that the movement party divides itself into two classes, the actors, and the students.”
—Ralph Waldo Emerson (1803–1882)
“He rides in the Row at ten o’clock in the morning, goes to the Opera three times a week, changes his clothes at least five times a day, and dines out every night of the season. You don’t call that leading an idle life, do you?”
—Oscar Wilde (1854–1900)
