Many years have passed since architect Andrea Ponsi settled in Florence, and still he feels he does not fully comprehend this mysterious city. The way Florence eludes understanding, however, can be an opportunity--to keep seeking, to keep exploring. Ponsi's Florence is endlessly suggestive. His tour of the city is one of continually shifting light and perspective, of stunning symmetry and an even more compelling asymmetry, of sudden transitions from bustling streets to the most perfect silence.

While Ponsi does consider such celebrated sites as the Piazza Santa Croce, the Ponte Vecchio, and the Duomo, the book is a decidedly personal view of Florence. The author notes the city's recurring geometry--the square courtyards, triangular spires, octagonal plaques and pillars--and marvels at a room almost too big to be called a room. He views the city from various terraces and likens the expanse of rising and falling rooftops to ocean waves.Here is Florence as labyrinth, possessing a medieval density that is relieved only by the sudden views of sky framed by its piazzas. Ponsi shows us a six-street intersection and ponders the abundance of acute angles, both indoors and out, in this city of infinite corners.

In Florence, humans and buildings commingle. The author equates haircuts and changes of clothes with fresh coats of paint and re-shingling jobs, and contemplates the way a human hand, feeling its way down a city block, adds to the patina of a stucco wall. Ponsi sees the city itself as a living body, through whose veins its inhabitants course.

This is the way we dream an architect could speak to us, fully communicating his passion. The book's elegant, concise prose--as well as its balance of the civic with the intensely personal--recalls the Calvino of "Marcovaldo" and "Invisible Cities." The text is accompanied by Ponsi's own spare but evocative watercolors and sketches, which, like his words, seek to behold rather than pin down. This lyrical tribute is as much an ode to the lost art of contemplation as it is to Florence--a city where every moment is different from every other moment.

Analogical thought is fundamental to creativity. The use of analogy can help to solve problems, make connections between disciplines, and use those relations to form original solutions. In Analogy and Design, Andrea Ponsi considers the role of analogical thought in architectural design. Almost all work on design and architecture is the result of analogical thinking, with respect to systems derived from nature, technical and scientific models, artistic experiences, and above all past models of architecture or objects. Ponsi considers the history of architecture through a series of examples that demonstrate the value of analogy as both creative technique and didactic tool. As an architect and product designer, Ponsi himself operates on a set of principles he terms ""analogous design""?a theory he developed that involves breaking down images into abstract elements, analyzing them, and then conceptually reassembling them in another form as a sort of parallel composition. In Analogy and Design, he looks at the principal models designers have utilized as their reference from the beginning to our own day: primary analogies, that is to say the human body, nature, and the abstract universe of signs; disciplinary analogies, taken from already existing examples of architecture and design; and analogies from outside the field, such as from music, literature, and the visual arts. The components are very different, but they maintain a similar relationship to each other. This methodology, Ponsi maintains, can be applied to compositions of a wide variety of types, including buildings, landscapes, household products, furniture, music, and literature. Merging scientific and academic research?so often limited to a specialized audience?Analogy and Design lays down the principles of analogous design, enabling a student or practitioner to ""see"" works and materials in a new way.

San Francisco is a city designed for artists and wanderers. From North Beach, to Chinatown, to the cold, rough surf of Ocean Beach, to Marin, both visitors and lifelong residents have endless opportunities to explore new neighborhoods, buildings, environments, and cultures just by getting in the car, hopping on a cable car, or by simply walking around the block.

In "San Francisco: A Map of Perceptions, " the architect Andrea Ponsi unravels the multifaceted beauty of one of America's favorite cities, introducing even those who have lived there for years to nuances often left unseen. Ponsi, a native of Florence who lived in San Francisco for many years, lyrically describes everyday life in the city, from a cafe in North Beach where he sits next to Lawrence Ferlinghetti, to the de Young Museum ("a solid mass, a rough but elegant body, faceted but compact") and the Academy of Sciences ("an ethereal, transparent building, lace made of glass and slender columns"), to Alcatraz ("an abandoned ship, a Flying Dutchman set adrift that bears the signs of a life of torment"), and even to the buffalo who reside in Golden Gate Park.

As with his book on Florence, Ponsi here reveals a deeply personal look at what it's like to live in and love a city. Having the unique perspective of having been both an insider and an outsider to San Francisco, he speaks to us in the way we dream an architect would, capturing the city's diverse yet emblematic structures through delicate watercolor and line drawings, while also offering poetic descriptions of the underlying smells, sounds, and light of its many neighborhoods.

A perfect balance of text and illustrations, "San Francisco: A Map of Perceptions" offers not only a guide for those visiting or returning to the city but also a compelling invitation for residents to revisit the utterly unique place in which they live.
