In 2010, Marina Abramović sat motionless and silent for six hours a day over three months during The Artist Is Present at New York’s Museum of Modern Art. Visitors queued—some overnight—for the single chair opposite her. The exhibition drew more than 850,000 visitors, while 1,545 people are recorded as having taken the seat during the 75-day performance. One participant remained for seven hours. Abramović recalled that people behind him became angry before recognising that waiting, too, had become part of the work. In most museums, a line leads to an artwork. Here, the pace of the queue was determined by another visitor participating in it. The freedom to occupy one silent seat and the accumulated time of everyone behind were made part of the same performance.
