Another is "Madama Butterfly" ("Madame Butterfly"), an opera in three acts (originally two acts) by Giacomo Puccini, with an Italian libretto by Luigi Illica and Giuseppe Giacosa. It is the story of a Japanese maiden (Cio-Cio San), who falls in love with and marries a white American navy lieutenant. After the officer leaves her to continue his naval service away from Japan, Cio-Cio San gives birth to their child. Cio-Cio San blissfully awaits the lieutenant's return, unaware that he had not considered himself bound by his Japanese marriage to a Japanese woman. When he arrives back in Japan with an American wife in tow and discovers that he has a child by Cio-Cio San, he proposes to take the child to be raised in America by himself and his American wife. The heartbroken Japanese girl bids farewell to her callous lover, then kills herself.
