Der Barbier von Bagdad: Der Barbier von Bagdad ("The Barber of Baghdad") is a comic opera in two acts by Peter Cornelius to a German libretto by the composer, based on "The Tale of the Tailor" and "The Barber’s Stories of his Six Brothers" in "One Thousand and One Nights".

Orpheus (Telemann): Orpheus (full title: Die wunderbare Beständigkeit der Liebe oder Orpheus, "The Wonderful Constancy of Love, or Orpheus") is an opera in three acts by the German composer Georg Philipp Telemann.  It was first performed in a concert version at the Oper am Gänsemarkt in Hamburg on 9 March 1726.  The anonymous libretto is based on "Orphée" by Michel du Boulay, originally set by the French composer Louis Lully.  Most of the work is in German but it also contains passages in French and Italian drawn from famous operas by Handel and Jean-Baptiste Lully.  The music to these words is Telemann's own, however.  The manuscript score of "Orpheus" was not rediscovered until the late 20th century.

List of battles involving the Ottoman Empire: The main battles in the history of the Ottoman Empire are shown below.  The life span of the empire was more than six centuries, and the maximum territorial extent, at the zenith of its power in the second half of the 16th century, stretched from central Europe to the Persian Gulf and from the Caspian Sea to North Africa.  The number of battles the empire fought is quite high.  But here only the more important battles are listed.  Among these, the battles fought in the 20th century (Turco-Italian War, Balkan Wars, and World War I ) as well as the sieges (like the sieges of Constantinople, Cairo, Belgrade, Bagdad, etc.) which most lists include as battles are not shown except in cases where the siege is followed by a battle (i.e. Vienna, Khotyn, Plevna).

George Barbier: George Barbier (] ) (1882–1932) was one of the great French illustrators of the early 20th century.  Born in Nantes, France on 16 October 1882, Barbier was 29 years old when he mounted his first exhibition in 1911 and was subsequently swept to the forefront of his profession with commissions to design theatre and ballet costumes, to illustrate books, and to produce haute couture fashion illustrations.  For the next 20 years Barbier led a group from the Ecole des Beaux Arts who were nicknamed by "Vogue" "The Knights of the Bracelet"—a tribute to their fashionable and flamboyant mannerisms and style of dress.  Included in this élite circle were Bernard Boutet de Monvel and Pierre Brissaud (both of whom were Barbier's first cousins), Paul Iribe, Georges Lepape, and Charles Martin.  During his career Barbier also turned his hand to jewellery, glass and wallpaper design, wrote essays and many articles for the prestigious "Gazette du bon ton".  In the mid-1920s he worked with Erté to design sets and costumes for the Folies Bergère and in 1929 he wrote the introduction for Erté's acclaimed exhibition and achieved mainstream popularity through his regular appearances in "L'Illustration" magazine.  Barbier died in 1932 at the very pinnacle of his success.  He is buried in Nantes.

Prosper-Didier Deshayes: Prosper-Didier Deshayes (mid 18th century – 1815) was an opera composer and dancer who lived and worked in France.  In 1764 he was a balletmaster at the Comédie-Française.  By 1774 he had become an assistant ("adjoint") at the Paris Opéra.  His first opera "Le Faux serment ou La Matrone de Gonesse", a "comédie mêlée d'ariettes" in two acts, was first performed on 31 December 1785 at the Théâtre des Beaujolais in Paris and became a popular success.  He went on to have another 18 works performed at various venues in Paris, but only two, "La faut serment" and "Zélie, ou Le mari à deux femmes", a 3-act "drame" first performed at the Salle Louvois on 29 October 1791, were ever published as musical scores.  He also participated in the collaborative Revolutionary opera "Le congrès des rois", a 3-act "comédie mêlée d'ariettes", which combined music written by Deshayes and 11 other composers and was first performed by the Opéra-Comique at the Salle Favart on 26 February 1794.  He died in Paris.

History of ecology: Ecology is a new science and considered as an important branch of biological science, having only become prominent during the second half of the 20th century.  Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics.  Its history stems all the way back to the 4th century.  One of the first ecologists whose writings survive may have been Aristotle or perhaps his student, Theophrastus, both of whom had interest in many species of animals and plants.  Theophrastus described interrelationships between animals and their environment as early as the 4th century BC.  Ecology developed substantially in the 18th and 19th century.  It began with Carl Linnaeus and his work with the economy of nature.  Soon after came Alexander von Humboldt and his work with botanical geography.  Alfred Russel Wallace and Karl Möbius then contributed with the notion of biocoenosis.  Eugenius Warming’s work with ecological plant geography led to the founding of ecology as a discipline.  Charles Darwin’s work also contributed to the science of ecology, and Darwin is often attributed with progressing the discipline more than anyone else in its young history.  Ecological thought expanded even more in the early 20th century.  Major contributions included: Eduard Suess’ and Vladimir Vernadsky’s work with the biosphere, Arthur Tansley’s ecosystem, Charles Elton's "Animal Ecology", and Henry Cowles ecological succession.  Ecology influenced the social sciences and humanities.  Human ecology began in the early 20th century and it recognized humans as an ecological factor.  Later James Lovelock advanced views on earth as a macro-organism with the Gaia hypothesis.  Conservation stemmed from the science of ecology.  Important figures and movements include Shelford and the ESA, National Environmental Policy act, George Perkins Marsh, Theodore Roosevelt, Stephen A. Forbes, and post-Dust Bowl conservation.  Later in the 20th century world governments collaborated on man’s effects on the biosphere and Earth’s environment.

Wozzeck: Wozzeck (] ) is the first opera by the Austrian composer Alban Berg.  It was composed between 1914 and 1922 and first performed in 1925.  The opera is based on the drama "Woyzeck", which was left incomplete by the German playwright Georg Büchner at his death.  Berg attended the first production in Vienna of Büchner's play on 5 May 1914, and knew at once that he wanted to base an opera on it.  From the fragments of unordered scenes left by Büchner, Berg selected fifteen to form a compact structure of three acts with five scenes each.  He adapted the libretto himself, retaining "the essential character of the play, with its many short scenes, its abrupt and sometimes brutal language, and its stark, if haunted, realism..."
