Incans Aztecs Mayans

"Three civilizations that produced architectural marvels, feats of civil engineering unmatched even today, mathematical and astronomical breakthroughs that modern scientists have only recently been able to match. Who were the Incans, Aztecs, and Mayans? And what motivated them to live as they did? John Holzmann examines their physical, social and spiritual cultures from a biblical perspective."--P.
