Jan 21 - Craig Howe - Director, Center for American Indian Research and Native Studies - Explorations of the Lakota Universe

Beginning over 200 years ago, traditional Lakota pictorial calendars, called "winter counts", recorded celestial events such as eclipses, comet sightings, and meteor showers that were seen in the Northern Plains skies. The dozens of diagrammatic drawings of these events are evidence that Lakota ancestors observed the night sky, and provide engaging origin points for this presentation to explore Lakota cosmology and star knowledge.
