From the myth of Arcadia through to the twenty-first century, ideas about sustainability, how we imagine better urban environments, remain persistently relevant, and raise recurring questions. How do cities evolve as complex spaces nurturing both urban creativity and the fortuitous art of discovery, and by which mechanisms do they foster imagination and innovation? While past utopias were conceived in terms of an ideal geometry, contemporary exemplary models of urban design seek technological solutions of optimal organisation. The Venice Variations explores Venice as a prototypical city that may hold unique answers to the ancient narrative of utopia. Venice was not the result of a preconceived ideal but the pragmatic outcome of social and economic networks of communication. Its urban creativity, though, came to represent the quintessential combination of place and institutions of its time.
