The work that launched Snohetta into the architectural big leagues was their Oslo Opera House, which will certainly rank among the firm's highlights whatever else they may do. Although this is by any measure a triumph of city planning, the building itself is not quite a masterpiece, though very fine indeed.

Architecture was the last of the major professions to devise a formal 'cursus honorum' before its practice could be undertaken.

Before World War II, Modernist architects sometimes had to resort to custom fabrication or outright fakery to achieve the machine imagery advocated by the Bauhaus after its initial, Expressionist, phase. Stucco masqueraded as reinforced concrete; rivets were used for decoration.

Architecture traditionally has been the slowest of art forms. It was not unusual for great cathedrals to take centuries to complete, with stylistic changes from Romanesque to Gothic or Renaissance to Baroque as common as the addition of chapels or spires. But because the function remained the same, the form could be flexible and its growth organic.

All architecture, classical or not, must have some sense of order, and order is much harder to achieve without the straight lines and right angles that have dominated the building art from time immemorial.

When Oscar Niemeyer died on December 5, 2012, ten days before his 105th birthday, he was universally regarded as the very last of the twentieth century's major architectural masters, an astonishing survivor whose most famous accomplishment, Brasilia, was the climactic episode of utopian High Modern urbanism.

Masterpieces of art possess immense potential to advance a worldview that could help assuage the societal terrors posed by globalization, the most thoroughgoing socioeconomic upheaval since the Industrial Revolution, which has set off a pandemic of retrogressive nationalism, regional separatism, and religious extremism.
