That is interesting! I take Fitz's point about the east and the west and the sun and moon being the most significant.
BUT
What did the ancients make of the unpolluted night sky? They didn't know that they were suns - so how did they explain them? Lamps of the gods, holes in the cloak of night, the gods themselves? The apparent patterns that stars make in the minds of mankind has meant that all cultures seem to have star legends and Orion is a big impressive guy. I take with a big pinch of salt a lot of the astronomical star rise alignments over stones, agricultural calendars etc. With so many stars and a ring of stones you can make any of them significant. But Orion coming up at the onset of winter does seem a bit different.
