Commonality of meaning
The images in each triad are interrelated. The courtyard in Florence, the fort in Oman and the corporate foyer in Tokyo for example, share a functional meaning. Just as the corporate foyer protects and acts as a portal to the corporate inner sanctum, the courtyard in Florence has a similar function protecting the family within. In Oman where water is precious, the function of the moat common in many western castles is replaced by the empty area inside the wall which surrounds the fort’s core, thus protecting the occupants and their supplies of food and water.
Similarly, the images of the girl show three completely different aspects of her personality, while at its core her character remains the same.
