DER_BLAUE_REITER(The Blue Rider)

Der Blaue Reiter (The Blue Rider) was a group of artists from the Neue Künstlervereinigung München in Munich, Germany. The group was founded by a number of Russian emigrants, including Wassily Kandinsky, Alexej von Jawlensky, Marianne von Werefkin, and native German artists, such as Franz Marc, August Macke and Gabriele Münter. Der Blaue Reiter was a movement lasting from 1911 to 1914, fundamental to Expressionism, along with Die Brücke which was founded in 1905.

7.3 ナチスによる弾圧

現代美術、特に19世紀半ば以降の芸術を理解せず毛嫌いしたナチスは、それらを「頽廃芸術」であると一方的にみなし、美術館などから作品を没収し芸術家に制作を禁じるなどして強力に弾圧した。ドイツ表現主義の作品もそのやり玉にあげられ、青騎士に属していた芸術家たちも例外ではなかった。

Contemporary art and especially the Nazis that understood and had an instinctive dislike of the art on and after the middle of the 19th century oppressed powerfully by considering that they are "Degenerate art" on a target on the other hand, confiscating a work from an art museum etc., and forbidding an artist work.
Neither the works of the German Expressionism nor the artists of those whom it made a victim of and that belonged to the blue knight were exceptions.

The origin of the cult and the time thereof are uncertain, as it is unknown whether the cult replaced the preceding Moai-based religion or had co-existed with it. Katherine Routledge was, however, able to collect the names of 86 Tangata manu.^[1]

Rongorongo_X_Birdman

Mural World(Birdmen)

Text X of the rongorongo corpus, known as the (New York) Birdman, is one of two dozen surviving rongorongo texts.

http://en.wikipedia.org/wiki/Rongorongo_text_X

Rongorongo is a system of glyphs discovered in the 19th century on Easter Island that appears to be writing or proto-writing.

The Tangata manu (bird-man), was the winner of a traditional competition on Rapa Nui (Easter Island). The ritual was an annual competition to collect the first Sooty Tern (manu tara) egg of the season from the islet of Motu Nui, swim back to Rapa Nui and climb the sea cliff of Rano Kau to the clifftop village of Orongo.
