Oh, Ursa minor, not Ursa major. Thank you for correcting me on this. Still doesn't confirm it was used to map anything, like you suggest. I don't know why you say "like the picture above"... This picture was never used to map anything, since it's a modern picture... Sorry, if I don't understand your point.

1. You said "It has been found in countless Christian artworks" - Can you prove it? If they are countless, you'd have no problem to give me one at least, right?

2. So, the point was the swastika in the hexagram... You sent me only a picture of a hexagram... I must again ask you to defend the specific symbol of swastika in a hexagram, please. Can you deliver such an example, or no?

3. Oh, and please give me the origin of the jewish swastika... :D I just now saw it. That's ludicrous if it were true.

Sorry, but the burden of proof falls onto you, since you shared the picture. Also, any of the other symbols would be useful knowledge to anyone to understand this symbology. And if those symbols were falsely attributed to the corresponding religions, as I suspect, this is useful knowledge too, wouldn't you agree?
