Lost Worlds by John Howe provides a magical look into 24 lost worlds, both legendary and real. Howe, who is famous for his illustrations for Lord of the Rings, brings all of these old civilizations to life. Stand on the mounds at Cahokia or look at the heat of the eruption that ended the city of Pompeii. This book is great for those who love King Arthur and other mythical heros of history as well.
