Question: Are both Eine florentinische Tragödie and Alceste operas?
Context: Eine florentinische Tragödie , Op. 16, is an opera in one act by Alexander von Zemlinsky to a libretto adapted by the composer from a German translation by of Oscar Wilde's unfinished play "A Florentine Tragedy". Mike McMahon was a programmer at the MIT Computer Science and Artificial Intelligence Laboratory during the 1970s who worked with Richard Stallman on Emacs.  He also wrote EINE, the first implementation of Emacs for Lisp machines with Daniel Weinreb.  EINE stands for "EINE Is Not Emacs".  EINE later became ZWEI (meaning, "ZWEI Was EINE, Initially"). Väter und Söhne – Eine deutsche Tragödie (1986) is an Italy-Germany TV mini-series, starring Burt Lancaster - Julie Christie and directed by Bernhard Sinkel. The Action of 8 June 1794 was a minor naval engagement of the French Revolutionary Wars, fought between the Sardinian frigate "Alceste" and the French frigate "Boudeuse", with eventually support from the 80-gun "Tonnant".  In the battle, "Alceste" manhandled "Boudeuse", but the engagement allowed the overwhelming "Tonnant" to arrive on the scene, forcing "Alceste" to surrender. The Eine (Lower Sorbian "Dupej") is a river, just under 40 km long in the German state of Saxony-Anhalt, which rises southeast of Harzgerode in the Harz mountains at 420 m above sea level.  The Eine flows north of the B 242 federal road to Friedrichsrode in an easterly direction and then swings northeast into the Harz Foreland.  The river channel runs through Alterode, Welbsleben and Westdorf to Aschersleben.  The tributaries of the Eine are the Wiebeck, the Leine, the Schwennecke, the Mukarehne and the Langetalbach.  Southeast of this town the Eine discharges into the Wipper at a height of 93.7 m above sea level. Faust: A Tragedy (German: "Faust.  Eine Tragödie" , or retrospectively "Faust.  Der Tragödie / erster Teil ") is the first part of "Faust" by Johann Wolfgang von Goethe, and is considered by many as the greatest work of German literature.  It was first published in 1808. Alceste, Wq.  37 (the later French version is Wq.  44), is an opera by Christoph Willibald Gluck from 1767.  The libretto (in Italian) was written by Ranieri de' Calzabigi and based on the play "Alcestis" by Euripides.  The premiere took place on 26 December 1767 at the Burgtheater in Vienna. The Birth of Tragedy from the Spirit of Music (German: "Die Geburt der Tragödie aus dem Geiste der Musik" ) is an 1872 work of dramatic theory by the German philosopher Friedrich Nietzsche.  It was reissued in 1886 as "The Birth of Tragedy, Or: Hellenism and Pessimism" (German: "Die Geburt der Tragödie, Oder: Griechentum und Pessimismus" ).  The later edition contained a prefatory essay, "", wherein Nietzsche commented on this earliest book. The non-profit organisation Jugend Eine Welt – Don Bosco Aktion Austria was founded at the inaugural meeting on 28 June 1997.  Following a reorganisation in January 2007 it has been called Jugend Eine Welt – Don Bosco Aktion Österreich.  Jugend Eine Welt Austria pursues the objectives of promoting aid to youth both nationally and internationally and sustainable development cooperation. Zmacs is one of the many variants of the Emacs text editor.  Zmacs was written for the MIT Lisp machine and runs on its descendants (Symbolics Genera, LMI Lambda, TI Explorer).  Zmacs is written in Lisp Machine Lisp (called ZetaLisp on Symbolics Lisp Machines).  It is based on the ZWEI programming substrate, which stands for "Zwei Was Eine Initially"; Zwei was a collection of routines which could be used to easily implement other programs, like the Symbolics mail program, "Zmail"- Eine stood for "Eine is not Emacs".
