Which cultural contributions come from western europe

The culture of  Western Europe has contributed to the world:

-Prehistoric Art
-Classical Art
-Medieval Art
-Neoclassical, Romanticism, and Realism
-Music (folk, classical)
-Prehistoric arquitecture ( like the Neolithic long house) 

The teachings of Jesus, such as the Parable of the Good Samaritan, are among the important sources for modern notions of Human Rights and the welfare measures commonly provided by governments in the West. Before the Cold War era, the traditional Western viewpoint identified Western Civilization with the Western Christian (Catholic-Protestant) countries and culture.

A cornerstone of Western thought, beginning in ancient Greece and continuing through the Middle Ages and Renaissance, is the idea of rationalism in various spheres of life, especially religion, developed by Hellenistic philosophy, Scholasticism, and humanism.
