A (not so) quick clarification
It has been over a year since I first started talking in posts about the angle of inclination between the ecliptic and the galactic plane. It was a major revelation for me. While searching - how is the solar system situated within the Milky Way? - I did notice lots of people asking the same question on forums. There's lots of info about where (Orion arm), but our orientation is rarely addressed.
I've gotten really slack about just weaving the concept into posts as though people have some familiarity with it. For those who don't, here is a link to the post where I first introduced the concept. Between the Sun and Galactic Plane
I will include an image at the bottom from Brian Fenerty, which was the first graphic representation I found on the internet. It came from a really cool astronomy page about how fast earth is traveling.
Not too long after finding some good graphics and learning how to set the view from the perspective of the Galactic Plane on Stellarium (free downloadable planetarium sodtware for your computer) , I rigged up a 12in earth globe at an angle to a table surface similar to our angle with the Galactic Plane. http://mpkellagher.blogspot.com/2016/03/trash-globe.html?m=1
So all this talk about Cetus the whale being on the midheaven when we face down into the bottom of the Milky Way, or Cygnus the swan being on the midheaven when we are turning down ... is related to our angle to the plane of the Milky Way.
To make sense of the constellation myths takes some focused meditation on actual heaven, as opposed to the heaven we grew up hearing about, but like Plato I think the angle of the spheres that the stories refer to are a lot more fascinating than the surface entertainment value. I know Socrates showed respect for the morally edifying qualities of the myths, but was inclined to censor the ones about gods behaving badly.
Timeaus, where I got the clue that the constellation stories were more than novel entertainment or edifying tales, is one of the few dialogues written by Plato that is not in the voice of Socrates. Socrates was more occupied with catching intellectuals sleeping at the wheel than actually teaching trigonometry or celestial mechanics. Plato used the voice of a younger man named Timeaus to outline some of the basic concepts of astronomy. I was lucky to find a well annotated side by side translation by Benjamin Jowett. I get a thrill out of unravelling the riddles of what appears to me to be a memory system infused with a timeless sense of humor.
I say 'appears to me' because I have yet to see any similar approach to the constellation stories outside Plato's Timeaus. I do not yet have a page dedicated to an explanation of the constellation stories that refer to the galactic plane, but I do have a page about the mechanics behind the mascots of the zodiac. I invite you to check it out and see if it makes sense to you.
So, to paraphrase Plato; there are two circles and they make a cross like the letter X.
If you're like me you'll think he's referring to the ecliptic and the celestial equator. I assumed Benjamin Jowett did not know what he was talking about when he said Plato meant one circle is the ecliptic and one is the galactic plane. Later, when studying the Fenerty image you see below, I saw the light. Ha ha.
There are 2 systems being poetically described in the stories of the old constellations. (This does not include constellations named after the time of Plato.) One system is the zodiac which explains the relationship of our tilted earth to the ecliptic. The rest of the old constellations like Pegasus, Perseus, Cassiopeia, Andromeda, Cetus and Orion (under world characters), Auriga, Canis Major, Argo Navis. Cygnus, Aquila (Milky Way coming up or Milky Way going down), then a couple from the upper dome of the galaxy - Ursa Major and my favorite, contained in the 26,000 year circle of the moving north pole, Draconis.
I know this is a lot of information to take in at one go. Please do not give up on making sense of heaven. It is worth your time to focus on these riddles when you are in a seriously meditative mood. Once you 'get' the stories the gods will be your good buddies for like for ever.
