These two stamps were issued in 2001 commemorating 100 years of death of Giuseppe Verdi, showing his operas:Un Ballo in Maschera and La Forza del Destino.
Giuseppe Verdi (1813–1901) was an Italian Romantic composer, mainly of opera. He was one of the most influential composers of the 19th century. His works are frequently performed in opera houses throughout the world and, transcending the boundaries of the genre, some of his themes have long since taken root in popular culture - such as "La donna è mobile" from Rigoletto, "Va, pensiero" (The Chorus of the Hebrew Slaves) from Nabucco, "Libiamo ne' lieti calici" (The Drinking Song) from La traviata and the "Grand March" from Aida. Although his work was sometimes criticized for using a generally diatonic rather than a chromatic musical idiom and having a tendency toward melodrama, Verdi’s masterworks dominate the standard repertoire a century and a half after their composition.
Un ballo in maschera (A Masked Ball), is an opera in three acts by Giuseppe Verdi with text by Antonio Somma. The libretto is loosely based on an 1833 play, Gustave III, by French playwright Eugène Scribe who wrote about the historical assassination of King Gustav III of Sweden. The subject was well known and had been used by other composers.
In 1792, the King of Sweden, Gustav III, was killed, the result of a political conspiracy against him. He was shot while attending a masked ball and died 13 days later from his wounds. For the libretto, Scribe retained the names of some of the historical figures involved, the conspiracy, and the killing at the masked ball. The rest of the play - the characterizations, the romance, the fortune-telling, etc. - is Scribe’s invention and the opera is not historically accurate.
However, in order to become the Un ballo in maschera which we know today, Verdi's opera (and his libretto) was forced to undergo a series of transformations, caused by a combination of censorship regulations in both Naples and Rome, as well as the political situation in France in January 1858.
La forza del destino (The Force of Destiny) is an Italian opera by Giuseppe Verdi. The libretto was written by Francesco Maria Piave based on a Spanish drama, Don Álvaro, o La fuerza del sino (1835), by Ángel de Saavedra, Duke of Rivas, with a scene adapted from Friedrich Schiller's Wallensteins Lager. It was first performed in the Bolshoi Kamenny Theatre of St. Petersburg, Russia, on 10 November 1862.
