Armida (Haydn)

Armida (Hob. XXVIII/12) is an opera in three acts by Austrian composer Joseph Haydn, set to a libretto based upon Torquato Tasso's poem Gerusalemme liberata (Jerusalem Delivered). The first performance was 26 February 1784 and it went on to receive 54 performances from 1784 to 1788 at the Esterháza Court Theatre. During the composer's lifetime it was also performed in Pressburg, Budapest, Turin and Vienna. Haydn himself regarded Armida as his finest opera. Armida then disappeared from the general operatic repertoire; it was revived in 1968 in a concert rendition in Cologne, and later a production in Bern. The United States premiere of the opera was given at the Palace Theatre in Manchester, New Hampshire, with the New Hampshire Symphony Orchestra for the Monadnock Music Festival in September 1981. Sarah Reese sang the title role; the director Peter Sellars set the production during the Vietnam War.Karl Geiringer has commented on how Haydn adopted the "principles and methods" of Christoph Willibald Gluck in this opera, and how the opera's overture alone encapsulates the opera's plot in purely instrumental terms. Haydn's opera contains occasional echoes of Sarti's Giulio Sabino, played at Esterháza in 1783.

Finnish nationalism

Nationalism was a central force in the History of Finland for the last two centuries. The Finnish national awakening in the mid-19th century was the result of members of the Swedish-speaking upper classes deliberately choosing to promote Finnish culture and language as a means of nation building—i.e. to establish a feeling of unity between all people in Finland including (and not of least importance) between the ruling elite and the ruled peasantry. The publication in 1835 of the Finnish national epic, the Kalevala, a collection of traditional myths and legends which is the folklore common to the Finns and to the Karelian people (the Finnic Russian Orthodox people who inhabit the Lake Ladoga-region of eastern Finland and present-day NW Russia), stirred the nationalism that later led to Finland's independence from Russia.

Nationalism was contested by the pro-Russian element and by the internationalism of the labor movement. The result was a tendency toward class conflict over nationalism, but in the early 1900s the working classes split into the Valpas (class struggle emphasis) and Mäkelin (nationalist emphasis).

Helen of Troy

In Greek mythology, Helen of Troy (Ancient Greek: Ἑλένη Helénē, pronounced [helénɛː]), also known as Helen of Sparta, was said to have been the most beautiful woman in the world. She was married to King Menelaus of Sparta but was abducted by Prince Paris of Troy after the goddess Aphrodite promised her to him in the Judgement of Paris. This resulted in the Trojan War when the Achaeans set out to reclaim her. She was believed to have been the daughter of Zeus and Leda, and was the sister of Clytemnestra, Castor and Polydeuces, Philonoe, Phoebe and Timandra.

Elements of her putative biography come from classical authors such as Aristophanes, Cicero, Euripides, and Homer (in both the Iliad and the Odyssey). Her story reappears in Book II of Virgil's Aeneid. In her youth, she was abducted by Theseus. A competition between her suitors for her hand in marriage saw Menelaus emerge victorious. An oath sworn by all the suitors (known as the Oath of Tyndareus) required all of them to provide military assistance to the winning suitor, whomever he might be, if she were ever stolen from him; the obligations of the oath precipitated the Trojan War. When she married Menelaus she was still very young; whether her subsequent departure with Paris was an abduction or an elopement is ambiguous (probably deliberately so).

The legends of Helen in Troy are contradictory: Homer depicts her as a wistful, even sorrowful figure, who came to regret her choice and wished to be reunited with Menelaus. Other accounts have a treacherous Helen who simulated Bacchic rites and rejoiced in the carnage she caused. Ultimately, Paris was killed in action, and in Homer's account Helen was reunited with Menelaus, though other versions of the legend recount her ascending to Olympus instead. A cult associated with her developed in Hellenistic Laconia, both at Sparta and elsewhere; at Therapne she shared a shrine with Menelaus. She was also worshiped in Attica and on Rhodes.

Her beauty inspired artists of all times to represent her, frequently as the personification of ideal human beauty. Images of Helen start appearing in the 7th century BCE. In classical Greece, her abduction by Paris – or escape with him – was a popular motif. In medieval illustrations, this event was frequently portrayed as a seduction, whereas in Renaissance paintings it was usually depicted as a "rape" (i. e. abduction) by Paris. Christopher Marlowe's lines from his tragedy Doctor Faustus (1604) are frequently cited: "Was this the face that launched a thousand ships / And burnt the topless towers of Ilium?"

List of military aircraft of the United States

This list of military aircraft of the United States includes prototype, pre-production, and operational types. For aircraft in service, see the list of active United States military aircraft. Prototypes are normally prefixed with "X" and are often unnamed (note that these are not the same as the experimental X-planes, which are not generally expected to go into production), while pre-production models are usually prefixed with "Y".

The United States military employs a designation and naming system to provide identifications to all aircraft types. Until 1962, the United States Army, United States Air Force (formerly Army Air Force), and United States Navy all maintained separate systems. In September 1962, these were unified into a single system heavily reflecting the Air Force method. For more complete information on the workings of this system, refer to United States Department of Defense Aerospace Vehicle Designations.

This list does not include aircraft used by the U.S. military services prior to the establishment of a numerical designation system. For these aircraft, see List of military aircraft of the United States (1909–1919). It also does not include aircraft designated under the pre-1962 United States Navy designation system. For these aircraft, see List of military aircraft of the United States (naval).

Sir John in Love

Sir John in Love is an opera in four acts by the English composer Ralph Vaughan Williams. The libretto, by the composer himself, is based on Shakespeare's The Merry Wives of Windsor and supplemented with texts by Philip Sidney, Thomas Middleton, Ben Jonson, and Beaumont and Fletcher. The music deploys English folk tunes, including "Greensleeves". Originally titled The Fat Knight, the opera premiered at the Parry Opera Theatre, Royal College of Music, London on 21 March 1929. Its first professional performance was on 9 April 1946 at Sadler's Wells Theatre.


Sylph (also called sylphid) is a mythological air spirit. The term originates in the 16th-century works of Paracelsus, who describes sylphs as (invisible beings) of the air, his elementals of air.Since the term sylph itself originates with Paracelsus, there is relatively little pre-Paracelsian legend and mythology that can be confidently associated with it, but a significant number of subsequent literary and occult works have been inspired by the idea. Robert Alfred Vaughan noted that "the wild but poetical fantasies" of Paracelsus had probably exercised a larger influence over his age and the subsequent one than is generally supposed, particularly on the Rosicrucians, but that through the 18th century they had become reduced to "machinery for the playwright" and "opera figurantes with wings of gauze and spangles."
