Astronomy Cast Ep. 216: Archaeoastronomy

http://www.astronomycast.com/archive/ From January 17, 2011. The Sun, Moon, stars and planets are visible with the unaided eye, and so there have been astronomers since before recorded history. Some of the earliest records we do have tell us what the ancient astronomers thought about the heavens, and how they used the changing night sky in their daily lives.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
