The Unchanging Sky

The unvarying aspect of the relationships of the stars' positions may have suggested to the ancients something that was analogous to their beliefs about the universe. It is not surprising that they chose to express their beliefs metaphorically, believing that groups of stars, constellations, and moving planets were associated with their deeply held stories of the creation, sustenance, and destruction of the universe. Human beings, even now, use metaphor to express deeply held beliefs, in the poetry and art of societies.

In more modern times some of the ancient designations for star arrangements have remained, giving us a flavor of what the world felt like when the sky was "closer". The names, positions and groupings of stars help us to give order to the sky in our minds.
