This issue deals with the past and the future, conservation and innovation. Innovation is an art. It is an art to know how to grant a new, unique vision to the world. It is because of this talent that I always regarded Francesco Borromini as one of the key innovators of his time and the one that laid the foundations for what we call parametric architecture today, or rather, the possibility to transform variable geometric entities into a calculated series to obtain something that is geometrically new. Transforming architecture into spacial innovation while still maintaining a relationship with established traditions was the key to Borromini’s success and the concept that inspired cityvision.
