Ancient Astronomy with Hannah Liu
Manage episode 406824981 series 3449035
What does the study of archeology, the study of the human past, offer to the astronomers of today? To find out, Dr. Charles Liu and co-host Allen Liu welcome archaeology expert Hannah Liu, MEd, to connect the past, the present, and the future of astronomy in an episode Allen has described as, “A Fistful of Lius.”
As always, though, we start off with the day’s joyfully cool cosmic thing, a recent scientific paper just published by archaeologist Federico Bernardini and astronomer Paolo Molaro which suggests that a 3,000-year-old stone tablet discovered near Trieste, Italy may be the oldest European star chart yet discovered.
Hannah, who is an expert in archaeology, takes us back to the hilltop area where the tablet was found, which had been occupied since the Iron Age, and was more than likely a farming area. She explains how early civilizations used the stars to keep track of planting and threshing seasons, which could support the theory that the tablet has an astronomical purpose.
Then, it’s time for our first question. Hannah teaches History at the Pingree School in South Hamilton, Massachusetts, which is where we got the questions we answer on today’s episode. Maeve asks, “Are we the only living things on earth who have a sense of how small we are in the universe?”
The Lius answer includes ancient Greeks, sea turtles who use stars for directions and moths that fly towards light thinking it’s the moon, and the beginnings of astronomy and astrology! Hannah explains how constellations and asterisms are cross-cultural, even though they have different names. In particular, The Pleiades is an example of star cluster relevant to cultures around the world.
Coming back to that 3000-year-old star chart, Hannah breaks down the 29 markings on the tablet, and how 28 of them are connectable to constellations that we know like Scorpius, Cassiopeia The Pleiades, and Orion. However, the 29th marking, near Orion’s Belt, still remains a mystery, and until we can pin it down, we can’t definitively claim it’s really a star chart.
Our next question comes from Abby, who asks, “Where do you think human involvement in space exploration is going?” Allen runs down the planned manned missions beyond low Earth orbit, where we haven’t gone since our last trip to the moon in 1972, along with the reasons we haven’t. We also hear how the stars were very important to ancient explorers like the Greeks and the Phoenicians, as well as the ancient Polynesian Wayfinders, who used the stars as their guides in their ongoing excursions around the world.
After brief sojourns into Star Trek and The Odyssey, we dive into ancient alien visitors, gods, and supernatural forces. Hannah points out the inherent Western biases in theories that “ancient aliens” were responsible for building the Pyramids and other impressive accomplishments that just happened to have been created in non-Western cultures of the past.
Charles explains that in the past, some people who used science and astronomy, like midwives and scientists, were accused of witchcraft and other equally disparaging and unfounded claims. This could create a divide between science and religion, but luckily, not an unbridgeable one – you’ll hear about Gerbert of Aurillac, a scientist who became Pope Sylvester II and brought the Abacus back to Europe, and how the Catholic Church itself established the Vatican Observatory which has made numerous discoveries over the years.
Finally, we get into the history and anthropology of museums, a subject about which Hannah will be teaching a course in the upcoming semester. What is the role of a museum? Is it science, education, or something else? Is it a place where we hold our treasures, or, increasingly, one where we recognize we hold other people’s treasures, some of which were once plundered and taken from those people against their desires? And yes, we do bring up situations like the Elgin Marbles and the British Museum’s refusal to return those artifacts to Greece... especially in light of the new U.S. law regarding repatriation of artifacts.
