The Pocket Books series is an assemblage of small publications which compile theoretical texts by various architects or institutions in different collections. These writings reflect different areas of interest and performance in the architectural discourse. For its second edition, written and compiled by Federico Bucci, the series reflects on the multidisciplinary work of Luigi Moretti (1906–1973). Moretti was the embodiment of the intellectual architect, capable of interweaving art and architecture, and his works are considered among the most original examples of Italian modernism. This book reveals the complex aspects of his theory on form and structure, space and time.
