In the early 1960s Italian design legend Bruno Munari published his visual case studies on shapes: Circle, Square, and, a decade later, Triangle. Using examples from ancient Greece and Egypt, as well as works by Buckminster Fuller, Le Corbusier, and Alvar Aalto, Munari invests the three shapes with specific qualities: the circle relates to the divine, the square signifies safety and enclosure, and the triangle provides a key connective form for designers.

One of the great designers of the twentieth century, Munari contributed to the fields of painting, sculpture, design, and photography while teaching throughout his seventy-year career. After World War II he began to focus on book design, creating children's books known for their simplicity and playfulness.

First published in 1976, this investigates the hidden uses and meanings of circles, squares and triangles in art and culture. From one of the greatest graphic designers of the 20th century.
