Pleiades (Mythology)

The seven daughter-nymphs of the Titan Atlas and the Oceanid Pleione — companions of Artemis, placed in the stars after Zeus transformed them to escape Orion's pursuit. The most globally recognised star group in human cultural history. Astronomical counterpart: pleiades-cluster. Crossing note: crossing-pleiades.

The Seven Sisters

Maia is the key figure connecting the Pleiades to the existing mythology × astronomy cluster. She is Hermes's mother — making the Pleiades the grandmother-cluster of the whole web: Orion pursues the Pleiades, Hermes is the son of Maia (a Pleiad), and Orion's mythology is already captured in crossing-orion-scorpius and myth-orion.

The Eternal Pursuit

Orion, the supreme hunter, pursued the Pleiades (or their mother Pleione) across the Earth for seven years. Zeus intervened, transforming them first to doves and then to stars. But the constellation of Orion still faces the direction of the Pleiades cluster — the pursuit continues across the sky for eternity.

Hesiod in *Works and Days*: "when the Pleiades flee mighty Orion and plunge into the misty deep... it is time to plough." The sisters mark the agricultural calendar precisely because Orion — winter — rises as they set; they — spring — rise as Orion sets.

The Lost Pleiad

Only six Pleiades are easily visible to the naked eye, though seven are named. The "lost Pleiad" was explained mythologically:

• Merope hides in shame because she married a mortal (Sisyphus) rather than a god — the only sister to do so
• Electra veiled herself in grief when Troy fell — she was the ancestral mother of the Trojans via Dardanus

Some scientists suggest the seven-sisters motif across cultures (found in Greek, Indigenous Australian, Japanese, and many other traditions independently) may date to 100,000+ years ago, when the star Pleione was separated enough from Atlas to be visible separately, giving a true seven-star naked-eye cluster.

Agricultural and Navigational Calendar

The name *Pleiades* likely derives from *plein* (to sail) rather than mythology — the heliacal rising of the Pleiades in May marked the start of Mediterranean sailing season; their setting in November marked its end. Hesiod's calendar is explicitly organised around their rising and setting. The name of the star cluster gave its name to the mythological sisters, not the other way around.
