Question: Hérodiade and Arlecchino, are which type of theatre?
Context: Site-specific theatre is any type of theatrical production designed to be performed at a unique, specially adapted location other than a standard theatre.  This specific site either may be originally built without any intention of serving theatrical purposes (for example, in a hotel, courtyard, or converted building), or may simply be considered an unconventional theatre space (for example, in a forest). Hérodiade is an opera in four acts by Jules Massenet to a French libretto by Paul Milliet and Henri Grémont, based on the novella "Hérodias" (1877) by Gustave Flaubert.  It was first performed at the Théâtre de la Monnaie in Brussels on 19 December 1881. The cuplé was a popular risqué Spanish theatre song style in the late years of the 19th century.  From 1893–1911 the songs were a feature of the "género ínfimo" (lowest type) cabaret theatre sung by solo female singers, or men in drag, and attended mainly by men.  But in the second decade of the 20th century the cuplé, in a more respectable form, became more family-friendly and was associated with the makings of stars of the Spanish theatre such as Aurora Jauffret, "La Goya". John Rich (1692–1761) was an important director and theatre manager in 18th-century London.  He opened the New Theatre at Lincoln's Inn Fields (1714), which he managed until he opened the Theatre Royal, Covent Garden (1732).  He managed Covent Garden until 1761, putting on ever more lavish productions.  He introduced pantomime to the English stage and played a dancing and mute Harlequin himself from 1717 to 1760 under the stage name of "Lun."  Rich's version of the servant character, Arlecchino, moved away from the poor, disheveled, loud, and crude character, to a colorfully-dressed, silent Harlequin, performing fanciful tricks, dances and magic.  The British idea of the Harlequin character was heavily inspired by Rich’s idea of a silent character.  Rich’s choice of being a silent character was influenced by his unappealing voice, which he was well aware of. Forum theatre is a type of theatre created by the innovative and influential practitioner Augusto Boal as part of what he calls his "Theatre of the Oppressed."  Boal created Forum theatre as a forum for teaching people how to change their world.  While practicing earlier in his career, Boal would apply 'simultaneous dramaturgy'.  In this process the actors or audience members could stop a performance, often a short scene in which a character was being oppressed in some way.  The audience would suggest different actions for the actors to carry out on-stage in an attempt to change the outcome of what they were seeing.  This was an attempt to undo the traditional actor partition and bring audience members into the performance, to have an input into the dramatic action they were watching.  Eventually this 'simultaneous dramaturgy' became Forum theatre when audience members were asked not just to suggest different actions, but to come on stage and perform their own interventions. Arlecchino, "oder Die Fenster" ("Harlequin, or The Windows", is a one-act opera with spoken dialog by Ferruccio Busoni, with a libretto in German, composed in 1913.  He completed the music for the opera while living in Zurich in 1916.  It is a number opera written in neo-classical style and includes ironic allusions to operatic conventions and situations typical of the late 18th and early 19th centuries.  It even includes a parody of a duel. Commedia dell'arte (] , comedy of the profession) was an early form of professional theatre, originating from Italy, that was popular in Europe from the 16th through the 18th century.  "Commedia dell'arte" also is known as "commedia alla maschera", "commedia improvviso", and "commedia dell'arte all'improvviso".  "Commedia" is a form of theatre characterized by masked "types" which began in Italy in the 16th century and was responsible for the advent of actresses (Isabella Andreini) and improvised performances based on sketches or scenarios.  A "commedia", such as "The Tooth Puller", is both scripted and improvised.  Characters' entrances and exits are scripted.  A special characteristic of "commedia dell'arte" are the "lazzi".  A "lazzo" is a joke or "something foolish" or "witty".  Another characteristic of "commedia dell'arte" is pantomime, which is mostly used by the character Arlecchino (Harlequin). The Jacobs Well Theatre was a playhouse in Cliftonwood, Bristol, England, which opened in 1729.  It took its name from the nearby Jacobs's Well, which may have been a mikveh, a type of Jewish ritual bath.  The theatre was built by actor John Hippisley, who had created the character of Peachum in the premiere of John Gay's Beggar's Opera.  The stage space was so small that actors exiting on one side had to walk around the building to re-enter on the other side, often being subject to banter by spectators enjoying this free show.  A hole was knocked through a party wall to an adjacent ale house, The Malt Shovel, so that actors, and audience seated on the stage, could obtain refreshments.  Admission prices ranged from 1 shilling to 3 shillings, and it was estimated that a full house could earn as much as £80.  Servants of patrons were admitted free of charge to an upper gallery.  In later years, Thomas Chatterton described the theatre as a "hut". An atmospheric theatre is a type of movie palace design which was popular in the late 1920s.  "Rather than seating the theatre patrons in a boxlike, formal setting as passive observers of stage entertainment, the atmospheric design transported them to an exotic European courtyard or garden.  A cerulean sky, often intricately dotted with accurately depicted starry skies with wispy floating clouds produced by a projector replaced the ornate domes of traditional theatre design.  Rather than crystal chandeliers and gilt ornamentation there were arches, trellises, balconies and statuary to evoke a sense of the outdoors.  Other ornamentation included trees, palms and vines and even taxidermy birds.  As the stars twinkled above, creating in the audience a sense of infinite space, when the entertainment was about to begin the lighting effects created an illusion of the setting sun, as colors changed from yellow to red to mauve.  The atmospheric theatre design made the patron an active, comfortable resident of an imaginary time and place, not a passive, aloof occupant of an oppressive formal space." The Type V ship is a United States Maritime Administration (MARAD) designation for World War II tugboats. Type V was used in World War II, Korean War and Vietnam War.  Type V ships were used to move ships and barges. Type V tugboats were made of either steel or wood hulls.  There were four types of tugboats ordered for World War II.  The largest type V design was the sea worthy 186-foot long steel hull, V4-M-A1.  The V4-M-A1 design was used by a number of manufacturers, a total of 49 were built.  A smaller steel hull tugboat was the 94-foot V2-ME-A1, 26 were built.  The largest wooden hull was the 148-foot V3-S-AH2, which 14 where built.  The smaller wooden hull was the 58-foot V2-M-AL1, which 35 were built.  Most V2-M-AL1 tugboats were sent to England for the war efforts under the lend-lease act. .  The type V tugs served across the globe during WW2 including: Pacific War, European theatre and in the USA.  The SS "Farallon" and other type V tugs were used to help built Normandy ports, including Mulberry harbour, on D-Day, June 6, 1944 and made 9 round trips to Normandy to deliver Phoenix breakwaters.
