Look up on any clear night and you can see myriad stars, planets, and the Milky Way stretching across the sky. The chances are that you know some of the constellations.
These are largely based on the mythology of the ancient Greeks. But they share remarkable similarities with the constellations of the oldest living cultures on the planet.
Hunters and sistersStellarium
Orion is constantly pursuing the seven sisters of the Pleiades. In the sky, Orion is defending himself from the charging bull Taurus, represented by the V-shaped Hyades star cluster. The Hyades are daughters of Atlas and sisters of the Pleiades.Stellarium
In Wiradjuri Aboriginal traditions of central New South Wales, Baiame is the creation ancestor, seen in the sky as Orion - nearly identical in shape to his Greek counterpart. Baiame trips and falls over the horizon as the constellation sets, which is why he appears upside down.Stellarium, Wiradjuri artist Scott 'Sauce' Towney
The Pleiades are called Mulayndynang in Wiradjuri, representing seven sisters being pursued by the stars of Orion.Stellarium, Wiradjuri artist Scott 'Sauce' Towney
In Aboriginal traditions of the Great Victoria Desert, Orion is also a hunter, Nyeeruna. He is pursuing the Yugarilya sisters of the Pleiades but is prevented from reaching them by their eldest sister, Kambugudha (the Hyades).
Scorpions and canoes
In Greek mythology, the scorpion that killed Orion sits opposite the hunter in the night sky as the constellation Scorpius. They were placed on opposite sides of the sky by the gods to keep them away from one other.Stellarium
A comparable relationship can be found in the traditions of the Torres Strait Islanders. The culture hero, Tagai, killed his 12-man fishing crew (Zugubals) in a rage for breaking traditional law, before they all ascended into the sky.
Tagai is standing on his canoe, formed by the stars of Scorpius. The Zugubals are represented by two groups of six stars: the belt/scabbard stars of Orion (Seg) and the Pleiades (Usiam). Tagai placed the Zugubals on the opposite side of the sky to keep them far away from him.Wikimedia/Osiris, CC BY-SA
Another famous constellation is Gemini, the twins, denoted by the bright stars Castor and Pollux.Stellarium
Many Aboriginal groups also view these stars as brothers. In the Wergaia traditions of western Victoria, they are the brothers Yuree and Wanjel, hunters who pursue and kill the kangaroo Purra.Stellarium, John Morieson and Alex Cherney
In eastern Tasmania, the constellation Gemini represents two ancestor men who created fire, walking on the road of the Milky Way – similar in orientation to the Greek constellation.
Bird flying highStellarium
In Wiradjuri traditions, Aquila is Maliyan, the Wedge-tailed Eagle. In some Greek and Wiradjuri traditions, the star Altair is the eagle’s eye - despite being seen in different orientations.Stellarium, Wiraduri artist Scott 'Sauce' Towney
Even Indigenous constellations around the world have noteworthy similarities.
The Emu in the Sky, seen by Aboriginal groups across Australia, is composed of the dark spaces in the Milky Way.Wiraduri artist Scott 'Sauce' Towney.
The rising of the celestial emu at dusk informs observers about the bird’s breeding behaviour. Across the Pacific, the Indigenous Tupi people of Brazil see the same shape as a rhea, a large, flightless bird that is native to South America and related to the emu.
The rhea’s behaviour is nearly identical to that of the emu and the Tupi and Aboriginal traditions are remarkably similar.
Why the similar stories?
What we don’t yet know is why different cultures have such similar views about constellations. Does it relate to particular ways we humans perceive the world around us? Is it due to our similar origins? Or is it something else?
The quest for answers continues.
The author would like to acknowledge and pay respect to Wiradjuri, Meriam Mir, Wergaia, and Aboriginal Tasmanian artists and elders for sharing their knowledge of the stars.
