At three o’clock the cotillion began. Emma did not know how to waltz. Everyone was waltzing, Mademoiselle d’Andervilliers herself and the Marquis; only the guests staying at the castle were still there, about a dozen persons.

One of the waltzers, however, who was familiarly called Viscount, and whose low cut waistcoat seemed moulded to his chest, came a second time to ask Madame Bovary to dance, assuring her that he would guide her, and that she would get through it very well.

They began slowly, then went more rapidly. They turned; all around them was turning⁠—the lamps, the furniture, the wainscoting, the floor, like a disc on a pivot. On passing near the doors the bottom of Emma’s dress caught against his trousers.
