Astronomy has been a favorite and significant component of mythology and religion throughout history. Astronomy and cosmology are parts of the myths of many cultures and religion around the world. Astronomy and religion have long been closely intertwined, particularly during the early history of astronomy. Archaeological evidence of many ancient cultures demonstrates that celestial bodies were the subject of worship during the Stone and Bronze Ages. Amulets and stone walls in northern Europe depict arrangements of stars in constellations that match their historical positions, particularly circumpolar constellations. These date back as much as 30,000–40,000 years.
