Something that pure fucks me up is that so many cultures around the world, from Europe to Indigenous Australians describe the Pleiades as a variant on seven sisters/maidens. Only six stars in the cluster are visible to the naked eye. There are stories from these diffuse cultures as to how one "sister" died or was hidden, usually from Orion the hunter.

About 100,000 years ago, a seventh star would have been visible but it moved so naked eye can't see its individual point of light any more.
