ForMontezuma, leader of the Mexicans, April 21, 1519 (known in theirsophisticated astronomical system as 9 Wind Day) was the precise date ofa dire prophesy: the return of Quetzalcoatl, a fearsome god predictedto arrive by ship, from the East, with light skin, a black beard, robedin black—exactly as Cortés would. The ensuing drama is described byeminent historian Maurice Collis in a style that is equal parts storyand scholarship. Though its consequences have been treated by writers asdiverse as D.H. Lawrence and Charles Olson, never before have the factsof this event been rendered with such extraordinary clarity andelegance.
