Context paragraphs:
Carmen de synodo ticinensi: The Carmen de synodo ticinensi ("Song of the Synod of Ticinum") is a poem of nineteen stanzas of five lines each in iambic trimeter.  Shortly after the Synod of Pavia (Ticinum) in 698, the "Carmen" was written down in a cursive hand on some blank pages in a copy of the acts of the Council of Chalcedon.  The same hand also added it to another manuscript.  It records that the assembled churchmen made heavy use of ancient texts, perhaps including the manuscript in which it was later written.  It is the principal contemporary source of the synod, which brought to an end the Schism of the Three Chapters in Italy.

Carmen: Carmen (] ; ] ) is an opera in four acts by French composer Georges Bizet.  The libretto was written by Henri Meilhac and Ludovic Halévy, based on a novella of the same title by Prosper Mérimée.  The opera was first performed at the Opéra-Comique in Paris on 3 March 1875, where its breaking of conventions shocked and scandalized its first audiences.

Verena Rehm: Verena Carmen Rehm, born 14 May 1984 in Neuburg, Bavaria, is best known as the backing vocalist and pianist of the Eurodance dance group Groove Coverage.  She has many song writing credits both within and outside the group and also sings for many other German dance acts.

María del Carmen (opera): María del Carmen is an opera in three acts composed by Enrique Granados to a Spanish libretto by José Feliú i Codina based on his 1896 play of the same name.  It was Granados's first operatic success and although largely forgotten today, he considered it to be his best opera.  At the end of its initial run in Madrid where it premiered in 1898, Queen Maria Cristina awarded Granados the Charles III Cross in recognition of his work.  The opera, sometimes described as a Spanish version of Mascagni's "Cavalleria rusticana" with a happy ending, is set in a village in the Spanish region of Murcia and involves a love triangle between María (soprano) and her two suitors, the peasant farmer, Pencho (baritone), and his wealthy rival, Javier (tenor).

Iolanta: Iolanta, Op.  69, (Russian: Иоланта ) is a lyric opera in one act by Pyotr Tchaikovsky.  It was the last opera he composed.  The libretto was written by the composer's brother Modest Tchaikovsky, and is based on the Danish play "Kong Renés Datter " ("King René's Daughter") by Henrik Hertz, a romanticised account of the life of Yolande de Bar.  In the original Danish play, the spelling of the princess's name was "Iolanthe", later adopted for the otherwise unrelated Gilbert and Sullivan operetta of that name.  The play was translated by Fyodor Miller and adapted by Vladimir Zotov.  The opera received its premiere on 18 December 1892 in Saint Petersburg.

King René's Daughter: Kong Renés Datter ("King René’s Daughter") is a Danish verse drama written in 1845 by Henrik Hertz.  It is a fictional account of the early life of Yolande of Lorraine, daughter of René of Anjou, in which she is depicted as a beautiful blind sixteen-year-old princess who lives in a protected garden paradise.  The play was highly popular in the 19th century.  It was translated into many languages, copied, parodied and adapted.  The Russian adaptation by Vladimir Zotov was used as the basis for the 1892 opera "Iolanta", written by Tchaikovsky, with libretto by his brother Modest Ilyich Tchaikovsky.

Tívoli (film): Tívoli is a 1974 Mexican comedy-drama film directed by Alberto Isaac and starring Alfonso Arau, Pancho Córdova, Lyn May and Carmen Salinas.  Loosely based on the true story of the last days of the Tívoli, an infamous variety theatre which had its heyday in the 1940s and early 1950s in Mexico City, the film, as its opening text claims, rather than give an historical account, aspires to evocate, in a nostalgic and humorous way, the atmosphere of the lively nightlife of that period, "which has disappeared forever."  Interweaved with burlesque performances with colorful costumes and sets, seductive stripteases and comedic variety acts, the film's main plot tells how a plan to tear down the theater by politicians, city officials, and property developers is met with resistance by the entertainers.

Spanish Love: Spanish Love is a three-act play by Avery Hopwood and Mary Roberts Rinehart, who adapted an earlier Spanish play, "María del Carmen" by Josep Feliu i Codina.  Producers Lincoln Wagenhals and Collin Kemper staged it at the Maxine Elliott Theatre on Broadway, where it opened on August 17, 1920.  Although critics had reservations about the play, the production was a success, running for over 300 performances.  However, the play's success was overshadowed by the tremendous popularity of "The Bat", another collaboration between Hopwood and Rinehart that opened on Broadway the following week.

The Sisterhood of the Traveling Pants: The Sisterhood of the Traveling Pants is a series of four bestselling young adult novels by Ann Brashares.  Released by Random House, the novels tell the continuing story of four young girls who acquire a pair of jeans that fit all four of them perfectly, even though they are all different shapes and sizes.  The four main characters are Lena Kaligaris, Tabitha "Tibby" Rollins, Bridget "Bee" Vreeland, and Carmen Lowell.
