I just discovered a field of study that I didn't know existed:

What is Archaeoastronomy?

The study of the astronomical practices, celestial lore, mythologies, religions and world-views of all ancient cultures we call archaeoastronomy. We like to describe archaeoastronomy, in essence, as the "anthropology of astronomy", to distinguish it from the "history of astronomy".

Enjoy!
