Fantastic and massive human-headed,
winged bulls and a curious wedge-shaped
writing system are the best-known legacies
of the place known as Mesopotamia.
Although these objects give some sense
of the grandeur and mystery of an ancient
culture, the influence of the region and its
people extends far beyond them. Long
described as the “cradle of civilization,”
Mesopotamia is clearly one of the earliest
civilizations in the world. Its many contributions
include the development of
written language, as well as several
advances in science, economics, law, and
religion. Mesopotamian astronomers, for
example, devised a 12-month lunar calendar
and divided the year into two seasons.
Mesopotamian mathematics is a sexagesimal,
or base 60, system, which survives
to this day in 60-minute hours and
24-hour days. The Sumerian calendar was
divided into seven-day weeks. Many of
these remarkable contributions are discussed
in the pages of this volume.
