On Thursday, May 2, Oldenburg Academy hosted astronomer Dean Regas from the Cincinnati Observatory for a talk titled "Archeoastronomy: Ancient Paths of the Sun, Moon, and Stars," which focused about what ancient artists knew about the stars and how we can learn about their knowledge though art.
Dean Regas started his talk about talking about all of the opportunities available to scientists and previewing his work, which includes television, podcasts, and work at the Cincinnati Observatory. Dean then moved to talk about what cave paintings show us about the knowledge of the ancients, especially in relation to astronomy.
Dean showed students photos of a pyramid called Chichen Itza where, as the sun moves, it looks like there's a serpent climbing down the steps -- and there's 91 steps, one for every 4 days of the year, plus a large one at the top. He showed students how the Temple of the Sun let individuals know that it was summer because of the precise placement of the window on the side of the temple.
