Peter Sís evokes a sense of fragile wonder and enduring discovery as the life of Galileo Galilei unfolds in this beautifully composed biography. Sís offers children multiple points of entry into the 17th century astronomer's life: through the brief, eloquent, understated prose; through snippets of information, including quotes from the Galileo and his contemporaries, that are artfully arranged on the pages; and through stirring, incomparable artwork that is as delicate and richly detailed as the heavens themselves. This exquisite 12 1/4 x 9 1/4" book, which took its title from Galileo's own book of the same name, will touch both the minds and the hearts of readers.
