This clip is an excerpt from the ABC-TV program Message Stick, in an episode called Before Galileo. The show delves into how Australia's Indigenous people read the night sky as a clock and a calendar for the year. Before Galileo, Aboriginal Australians had a sophisticated cosmology, and before Copernicus they knew the world was round.
