Changing Sunset Position

Changing position of Sunrise from a fixed location over a year

The changing position of Sunrise throughout a year from a fixed location. The further north or south of the equator we live the more extreme our seasonal changes and the bigger shifts we perceive in the sunrise or sunset position during the year.  In such harsh and changing seasons it would also have been the more important for ancient cultures to mark the seasons.

Using the landscape to mark the seasons like this is called a horizon calendar. But what if your horizons are flat and featureless, or you require more accuracy, or you’re a powerful priest and wish to theatricise important changes in time?

Then ‘perhaps’ you construct an artificial horizon by placing large stones to mark the progress of the Sun – a henge.
