art works reveals the otherwise ideas and impulses of a society
I agree that art works reveal otherwise ideas and impulses of a society. These art works consistently see a reflection of religion, politics, science and so on.
Art works is a distinct reflection of religion. This quality is especially evident in Middle Ages. In Middle Ages, Roman Pope imposes rigid restrictions on human thoughts as well as art works therefore religion is dominant in the themes of paintings. Generally these paintings are about the birth of Christ and Resurrection or so on. Not only the paintings are impinged by religion but also is architecture. Nowadays, we often associate Gothic constructions with Theology. Old castles are typical symbol of rigid hierarchy. Many famous churches such as Milan church, Paris indicate the monopolizing status of Christian in Middle Ages. In short, Christian is preoccupied in art works in middle ages.
Art works also reflect political situation of certain period. Beethoven's third Symphony is a hymn of French Revolution. The music praises revolutionary people with passionate and solemn melody. Marseillaise is created during the period when foreign countries invade French. This piece of music greatly encourage people when French capitalism revolution is at stake. In short, music often serves as a useful weapon especially there is a revolution.
Art works reflect the development of technology. Stepped into 20th century, more and more technological factors are used in art works. Due to the help of technology, art works also make much progress. Consider the fantasy film "Lord of Rings" as an example. This film wins 11 Oscar awards by apt technological method such as 3D. Digital music is also a good example of combination of art and science. Moreover, skyscraper buildings dominate public architecture. All these forms reflect the impact of technology development on art.
In sum, art works reveal otherwise ideas and impulses of a society. These art works consistently see a reflection of religion, politics, science and so on. As all fields of a society is closed related, art is certainly reflection of other fields.
