When half the Christchurch CBD had to be demolished following the earthquakes, the first signs of recovery came in the form of art emerging in vacant lots.
Much of the work was just fun. Later there was wry political comment; some of it suggested what had been there before the disaster, although all relayed the same message: We are still here.
The growth in public art following catastrophes was repeated that year after the Japanese tsunami, and before that in New Orleans after Hurricane Katrina. It raises this question: In the wake of events that lead to loss of life, homelessness, and a lack of clean water and food, why do people still make and display art - often more than when society is functioning? The answer is simple: We need to.
However, our fundamental urge to express ourselves in this way is the first thing to be forgotten when publicly funded art attracts opposition from those claiming to have the best interests of ratepayers in mind. Often these critics make arguments based on the three main myths of public art.
The first myth is that such projects are "the icing on the cake" - not core business - and councils should concentrate on providing basic amenities.
