The book is perhaps most impressive for Heilbrons deep immersion in the rich context of his story, particularly the personal, social, and intellectual relations among lesser actors who are often treated as mere names while the spotlight shines on Galileo. Michael H. Shank, Science & Education Heilbron has produced that rare marvel, a splendid new view of a familiar figure, a witty, absorbing, and convincing account of the man and his epoch, destined for the wide readership Galileo himself once had.
