    This fictionalized version of a true story emphasizes the importance of artistic vision and personal resilience. Editorial Reviews In fifteenth century Florence, a contest is announced for the best design of a dome for the Cathedral of Santa Maria del Fiore. Filippo Brunelleschi, a goldsmith called Pippo the Fool for his practice of designing peculiar machines and structures, vows to win. No one has been able to figure out how to build a dome of the necessary size. Pippo studies the problem and prepares sketches. The contest judges eliminate him. But he builds a model, and the judges are impressed. However, to his anger, they insist that he work with the sneering, arrogant Lorenzo Ghilberti. Overcoming his pride, Pippo begins. It takes sixteen years to finish—without Ghilberti—but the result is the marvel we can see today. Estrada takes pains to depict Florence with historic thoughtfulness. At the same time, his characters are effectively humorous. Lorenzo is depicted with foolish bravado, while Pippo has youthful arrogance. The detailed watercolor-and-gouache scenes with crowds of citizens are informative as well as attractive; the images of the building in process and finished at last are truly impressive. Notes by both author and illustrator add factual information. Includes a list of resources for those who want to learn more. Reviewer: Ken Marantz and Sylvia Marantz
