There can be little question that the tall building presents one of the most difficult challenges to the architect.

There is no sadder tale in the annals of architecture than the virtual disappearance of the defining architectural form of the Modern Movement - publicly sponsored housing.

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.

During the modern period, the vanguard architect has usually relied on small residential jobs both to supply a steady income and to serve as 'sketches' for ideas that are often later translated to the larger scale of public commissions.

Considering my specialization in architecture, I'm not surprised that the first graphic novel to thoroughly engage, not to say captivate, me is Chip Kidd and Dave Taylor's 'Batman: Death by Design.'

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.

Winning the Pritzker assures a flood of work in one's seventies and eighties, jobs necessarily carried out by assistants as the demands of modern-day cultural stardom and the inevitable waning of physical capacities prevent many architects from attaining the transcendent final phase more easily achieved by artists in other mediums.
