Ren Zi, the fifth year of the Hongxi reign.
So a book about a year is fundamentally ahistorical if it treats the events that occurred between January 1 and December 31, by Western reckoning, of a given year as a coherent entity. Most people would not have thought of those days as constituting a year, any more than any other combination of days amounting to about 365 in all—or 260 days, or 330, or whatever other number happened to be conventional in their culture. In any case, no sequence of days encloses events so discrete that they can be understood except in a longer context. So in this book therules shall be flexible about dates, ranging back and forth from what we now think of as 1492 into adjoining years, decades, and ages.
A book like this, moreover, is necessarily about more than the past. Because we are imposing a modern notion of a year on people unaware of it at the time, this book, like other histories of particular years, is self-condemned to be retrospective. It is as much about us—how we see the world and time—as about people in the past. Historians’ job is not to explain the present but to understand the past—to recapture a sense of what it felt like to live in it. But, for present purposes, I want to depart from my usual historian’s chores. What I expect readers of this book to want to know about 1492 is not only or even primarily what it felt like to experience it, because most people had no sense of experiencing anything of the sort, but what its events contributed to the world we inhabit now.
Still, a year really did mean something, in a way no longer easily accessible to us in urban, industrial or postindustrial environments. The succession of seasons is hardly noticeable, except superficially—as hemlines rise and fall with the mercury in the thermometer, and as the density of clothing matches cloud cover. Heating and insulation indemnify us against summer and winter. U.S. homes are now typically hotter in winter than summer, thanks to the ferocity of the boilers and the frigidity of the air-conditioning. Global trade brings out-of-season food even to relatively poor people in relatively rich countries. Most modern Westerners have lost the lore of knowing when to eat what.
In 1492, almost the entire world lived by farming or herding, and the whole of the rest by hunting. So the cycle of the seasons really did determine almost everything that mattered in life: the rhythms at which crops grew or animals migrated determined what one ate, where one lived, what clothes one wore, how much time one spent at work, and what sort of work one did. Reminders of the passage of time, carved on church doors for worshippers to see as they entered, commonly included scenes, arrayed month by month, of the activities the cycles of weather regulated: typically, tilling in February, pruning in March,hawking in April, mowing in June, grape treading in October, plowing in November. Japanese poems conventionally began with invocations of the season. Chinese writers associated each season with its appropriate food, clothes, and decor. The whole world lived at a pace and rhythm adjusted to the seasons.
Everywhere people watched the stars. In Mediterranean Europe, the motions of Orion and Sirius, as they climbed to midsky, signaled the wine harvest. The rising of the Pleiades announced harvest time for grain, their setting the time to plant. The Maya watched the motion of Venus anxiously, because the planet governed days propitious respectively for warmongering and peacemaking. Muhammad had taught Muslims that new moons are “signs to mark fixed periods for men and for the pilgrimage.” 15 In China, astronomers were vital policy consultants, because the prosperity of the empire depended on the accurate timing of imperial rites according to the motions of the stars, and part of the emperor’s duty was to monitor the skies for signs of celestial “disharmony.” For this was a world without escape from the
