Irish Mythology - The Milky Way

Some Irish historians believe that 5000 years ago like see you've got this place New Grange and whoever the fuck built New Grange had knowledge of astronomy. Some people think that they called the bind valley the way of the white cow because remember I spoke earlier about the other world that the other world was like a parallel universe. On a clear night when you look up at the sky you would see the milky way the stars in the sky and this whiteness would then be reflected in the river so the thought that like the bind river had an otherworldly parallel up in the sky is fascinating.
