What I find interesting is the scorpion. Why should the two continents have the same celestial imagery?

Probably because Scorpio is one of the few constellations that actually looks like what it's suppose to be.

[From many - one.]

I'll have to check, but there are similarities in the name also.

And it doesn't look like a scorpion to me, it looks like a fish hook.

Part of the trick is defining the borders.
