The Disappearing Star and The Oldest Story Ever Told
Across continents and centuries, a hauntingly similar story appears: a cluster of stars once had one more member — and then one went missing. Many cultures tell of “Seven Sisters,” even though most people can now see only six bright stars with the naked eye in the cluster known as the Pleiades (also cataloged as Messier 45).
This mismatch between name and visibility has sparked a fascinating question: are these just poetic myths, or are they preserving a real celestial memory?
A Shared Myth Across the World
- In ancient Greece, the sisters were immortalized as companions of Artemis, daughters of Atlas (Greek mythology) and Pleione (mythology). One sister is said to have dimmed or vanished out of shame, grief, or love.
- Among Indigenous Australian cultures, including the Pitjantjatjara people, the cluster is also remembered as a group of sisters, and stories speak of one lost or hidden member.
- Traditions across North America, Asia, and Europe echo the theme of a vanished sister or lost star.
That such distant cultures share nearly the same narrative is one of the more tantalizing clues in cultural astronomy.
Could the Stories Reflect a Real Event?
Astronomers point out that stars in the Pleiades vary in brightness over time. One candidate for the “missing sister” is the star Pleione — a variable star whose brightness changes over long periods. Thousands of years ago, Pleione may have shone brighter, clearly visible to the naked eye, before dimming enough to slip out of easy sight.
If true, then the legends might preserve a real observational memory stretching back millennia — a remarkable case of oral tradition capturing long-term astronomical change.
