chunk: Written by Alexandre Dumas, fils, (1824–1895) when he was 23 years old, and first published in 1848, La Dame aux Camélias is a semi-autobiographical novel based on the author's brief love affair with a courtesan, Marie Duplessis. Set in mid-19th century France, the novel tells the tragic love story between fictional characters Marguerite Gautier, a demimondaine, or courtesan, suffering from "consumption" (tuberculosis), and Armand Duval, a young bourgeois. Marguerite is nicknamed la dame aux camélias (French for 'the lady of the camellias') because she wears a red camellia when she's menstruating and unavailable for making love and a white camelia when she is available to her lovers.
