While changes in the art usually occurs from time to time, the art of the last century seems to change during short periods of time. With World War and technological changes, changes in artistic expression and the media. For a clearer picture of change through art, let us think about the changes made in the 20th century. Art ideas changed drastically during the 20th century.

Fauvism from France and Germany in Bruke brought by Post Impressionism and Art Nouveau of the 19th century. This is from the period of Modernist art.

A color representation that is not the main focus of French Fauvism in figurative painting. Emotion is the focus of Die Brucke. The Renaissance movement was challenged by the Cubism of Picasso art. Machine age focus on Futurism. In Russia, Suprematism is a large movement. Surrelism Dadism evolved from attacking the ideas of art and undermine the cultural differences of low and high. Surrelism reveal the subconscious and influenced by the automatism.

Freud making steps in Psychology and this causes the images of dreams and the unconscious by artists like Salvador Dali. Jackson Pollock and Mark Rothko revealed a separate image in the 1950s. commercial imagery began with Andy Warhol. He minimized the art and these changes were brought from Modernism to Post Modernism. This is a great art movement. The change from Modernism to Post Modernism brought a change in the art and are also used installation art, intermedia art and conceptual art. This movement believes in the importance of learning. They also believe that you can not only learn the knowledge you really need use it against something. This is the art of disappointment. This expresses these ideas. Post Modernism and cultural sentiments expressed rejection of the ideas of the past generation. Most artists Post Modernism rejected the ideas brought from the Renaissance and Modernist periods.

Art changes in culture and society. You can tell a lot about the culture through art and through changes in the art. To learn about the community, you must learn about their art. Study of changes and major events that changed the art. This is all important. You will find that artists are the changes they feel and they see the world around them. They tend to be cultural eye. Sometimes it can change the cultural arts and other arts seem to times of cultural change. This is a strange relationship to be studied. There are many articles online that you can read and also a lot of books in the library if you want to learn more about this. You will find that this is a very interesting area to be studied.

The pattern was soon identified as the sankofa — a symbol printed on funereal garments in West Africa — and it captured the imagination of scholars, preservationists and designers. Ultimately, it was embraced by many African-Americans as a remarkable example of the survival of African customs in the face of violent subjugation in early America.

The sankofa was widely invoked in 2003, when the 419 remains were reinterred at the site, now known as the African Burial Ground, following painstaking examination. It was chiseled into a black granite memorial unveiled in 2007. It is featured in an interpretive display in the federal building at 290 Broadway (the construction of which led to the discovery of the graves), which describes it as a direct link to “cultures found in Ghana and the Ivory Coast.” And it serves as a logo for the African Burial Ground as a whole.

Michael A. Gomez, a professor of history at New York University and an authority on the African diaspora, said the design’s apparent link to 18th-century Africa “is of enormous meaning and carries a lot of symbolic weight.” For decades, historians and anthropologists have debated the extent to which the continent’s cultural practices endured and came to influence art, language, music and religion in the Americas — a question with particular resonance for the African-American community.

The burial ground sankofa was important in this debate, Dr. Gomez said, “because, let’s face it, we don’t have an extremely large amount of material culture with which to work.”

But now a peer-reviewed study, published this month in a leading history journal, argues that the heart-shaped symbol is not, in fact, a sankofa, and probably does not have African origins at all. Indeed, it suggests that the sankofa probably did not yet exist as a symbol in Africa at the time the coffin was made, and that the design is likely Anglo-American in origin.

The National Park Service, which has managed the burial ground since it was a declared a national monument in 2006, is itself stepping back from the original claim. As a result of research by scholars who prepared reports in 2006 for the federal government, the interpretive sign in the service’s new $5.2 million visitor center, scheduled to open on Feb. 27, will say only that the design “could be a sankofa symbol” and that “no one knows for sure.”

In an interview, Erik R. Seeman, the historian whose new study treats the sankofa claim skeptically, acknowledged that his argument could be politically fraught. In his article, published in the January issue of The William and Mary Quarterly, he makes a point of emphasizing his belief that African influences did play a major role in the lives of early black Americans — although generally as part of hybrid traditions.

“As free and enslaved blacks created a distinctive culture in the New World, they drew on remembered African practices and Anglo-American religious and material culture to fashion something altogether original,” wrote Dr. Seeman, who teaches American history at the University at Buffalo. Dr. Seeman’s article, adapted from a book, “Death in the New World: Cross-Cultural Encounters, 1492-1800,” to be published in May by the University of Pennsylvania Press, argues that scholars “have too readily attributed cultural practices to African antecedents without convincing documentary or archaeological evidence.”

After archaeologists who examined the bones “emphasized the African origins” of the beads, shells, rings and other objects in the graves, Dr. Seeman writes, “historians followed this lead, seeing in the African Burial Ground artifacts glimpses of a long-hidden African worldview in New York.”

Particularly striking was the coffin labeled Burial 101, containing the remains of a man between 26 and 35 who died sometime after 1760. (Some of the tacks within the heart-shaped symbol can be read as the number “69,” suggesting that the man died in 1769.)

The hexagonal, larch-wood lid of the coffin was studded with 187 cast-iron tacks, 51 of which made up the heart-shaped pattern, about 18 inches wide and 19 inches high.

“It can be safely concluded,” Kwaku Ofori-Ansa, an expert in African art at Howard University, wrote in a 1995 newsletter of the archaeological excavation, “that the image was meant to be” the sankofa — one of several hundred symbols that are stamped on adinkra cloth, used by the Akan people of present-day Ghana and Ivory Coast.

Although a series of reports produced for the African Burial Ground project in 2006 backed away from this definitive stance — stating only that the design “has been interpreted” as a sankofa — it was nevertheless used as a central element in the granite memorial completed the next year at a cost of more than $5 million
