The builders of Stonehenge five millennia ago revered the long cycles of time. Their monument measured the annual rhythms of the sun from equinox to equinox and the subtle 18.6-year oscillations of the rising moon. Through a hundred generations, they revised and recalibrated their circles of earth and stone to bind their lives with celestial time.

Their Long Count calendar encompassed cycles that stretched 5, 000 years, from the primordial origins of life to the imponderable beginnings of a new era.
