A climate defined by wet and dry seasons, a mostly mountainous terrain, a biota prone to disturbances, a human geography characterized by a diversity of peoples all of whom rely on burning in one form or another: Mexico has ideal circumstances for fire, and those fires provide a unique perspective on its complex history. Narrating Mexico's evolution of fire through five eras, historian Stephen J. Pyne describes the pre-human, pre-Hispanic, colonial, industrializing (1880-1980), and contemporary (1980-2015) fire biography of this diverse and dynamic country. Creatively deploying the Aztec New Fire Ceremony and the "e;five suns"e; that it birthed, Pyne addresses the question, "e;Why does fire appear in Mexico the way it does?"e; Five Suns tells the saga through a pyric prism. Mexico has become one of the top ten "e;firepowers"e; in the world today through its fire suppression capabilities, fire research, and industrial combustion, but also by those continuing customary practices that have become increasingly significant to a world that suffers too much combustion and too little fire. Five Suns completes a North American fire-history trilogy written by Pyne over the past 40 years, complementing his histories of Canada and the United States.
