Questions are grouped in sections according to the number of items in their answer (all the 3s, all the 4s, all the 5s, etc.), so that the answers are in the form of easily memorized lists. You won't find Luther's 95 theses, or the 264 Popes, for example, but you will find everything from the 3 sons of Adam and Eve all the way up to the 24 letters of the ancient Greek alphabet.
This clever format lends itself well to quizzing and guessing, which gives it a deliciously sophisticated parlor-game quality. But for those who wish to delve a little deeper, there are thoughtful essays to go with each answer that include fascinating details and place the list in its larger cultural or historical context. Much more than a book of trivia, What Are the 7 Wonders of the World? offers a grand overview of the knowledge needed to appreciate many of the finest things in our cultural and intellectual life.
