Erik Belton Evers Bruhn (3 October 1928 – 1 April 1986) was a Danish danseur, choreographer, artistic director, actor, and author.
The Renaixença (] , ] (also written "Renaixensa" before spelling standardisation) was an early 19th-century romantic revivalist movement in Catalan language and culture, akin to the Galician Rexurdimento or the Occitan Félibrige movements.
 The movement dates to the 1830s and 1840s, but lasted into the 1880s, when it branched out into other cultural movements.
 Even though it primarily followed a romantic impulse, it incorporated stylistic and philosophical elements of other 19th century movements such as Naturalism or Symbolism.
 The name does not indicate a particular style, but rather the cultural circumstances in which it bloomed.
A noble savage is a literary stock character who embodies the concept of the indigene, outsider, wild human, or "other" who has not been "corrupted" by civilization, and therefore symbolizes humanity's innate goodness.
 In English, the phrase first appeared in the 17th century in John Dryden's heroic play "The Conquest of Granada" (1672), wherein it was used in reference to newly created man.
 "Savage" at that time could mean "wild beast" as well as "wild man".
 The phrase later became identified with the idealized picture of "nature's gentleman", which was an aspect of 18th-century sentimentalism.
 The noble savage achieved prominence as an oxymoronic rhetorical device after 1851, when used sarcastically as the title for a satirical essay by English novelist Charles Dickens, whom some believe may have wished to disassociate himself from what he viewed as the "feminine" sentimentality of 18th and early 19th-century romantic primitivism.
"Zdravljica" (] ; English: "A Toast") is a "carmen figuratum" poem by the 19th-century Romantic Slovene poet France Prešeren, inspired by the ideals of "Liberté, égalité, fraternité".
 It was written in 1844 and published with some changes in 1848.
 Four years after it was written, Slovenes living within Habsburg Empire interpreted the poem in spirit of the 1848 March Revolution as political promotion of the idea of a united Slovenia.
 In it, the poet also declares his belief in a free-thinking Slovene and Slavic political awareness.
 In the late 1980s, it was adopted as the national anthem of Slovenia.
Carla Fracci (] ; born 20 August 1936, Milan) is an Italian ballet dancer and actress.
 Thanks to her extensive career and her acclaimed interpretation of several classical romantic ballets such as "La Sylphide", Fracci became one of the most experienced and recognized interpreters of Romantic ballets.
 “As Erik Bruhn once said, [Fracci] gave the world a new idea of the ballerina in 19th-century Romantic ballets.”
 Her career highlights include "Nijinsky", "Giselle" (American Ballet Theatre), Complete Bell Telephone Hour Performances: Erik Bruhn 1961-1967.
Oybin is a municipality in the Görlitz district, in Saxony, Germany, located very close to the border of the Czech Republic.
 Following the defeat of the Protestant armies by the Habsburgs in the Battle of the White Mountain in 1620, many Protestant Czechs found refuge across the border in the hills of Upper Lusatia.
 It is a ""Kurort"", a resort or spa certified by the state, where people go for rest and recuperation.
 It is most famous for its mountain of the same name, an exposed natural sandstone dome that towers above the town.
 The ruins of a medieval monastery lend a wild romantic beauty to it and it was a favorite subject of 19th-century Romantic painters like Caspar David Friedrich.
 Many bizarrely shaped geological rock formations can be found in the surroundings.
 The scenic narrow gauge Zittau–Kurort Oybin/Kurort Jonsdorf railway runs from Oybin to Bertsdorf, from there to the neighboring municipality of Jonsdorf and the town of Zittau.

The Parc del Laberint d'Horta (] , "Labyrinth Park of Horta", sometimes named Jardins (Gardens) del Laberint d'Horta) is a historical garden in the Horta-Guinardó district in Barcelona and the oldest of its kind in the city.
 Located on the former estate of the Desvalls family, next to the Collserola ridge, the park comprises an 18th-century neoclassical garden and a 19th-century romantic garden.
Ross Priory is an early 19th-century country house located west of Gartocharn, West Dunbartonshire, on the south shore of Loch Lomond, Scotland.
 From the 14th century the estate, known as The Ross, was owned by a branch of the Buchanan family of Buchanan Castle, who built a house here in 1695.
 The present house is the result of remodelling by James Gillespie Graham and was complete in 1816.
 The term "priory" does not imply ecclesiastical provenance, but is simply a 19th-century romantic affectation.
 Sir Walter Scott spent time at Ross Priory in the years following the rebuilding.
 It was owned by subsequent members of the Leith-Buchanan family until the later 20th century.
 In 1973 it was sold to Strathclyde University and now serves as a recreational and conference centre.
