Gemini crossed arms imagery

[Koen G]

I just noticed something pose-related: the male "gemini" has his arms crossed. This makes it look less like embracing, and more like a double handshake.
Has this been noted before? 

Several people here have studied many other zodiacs. Is this something that returns? It seems like a very deliberate and significant cultural pointer to me. You don't "just" let people "embrace" with a double handshake.

I'm focusing my efforts on the balneo section so I'm not going to look into this at the moment. Just wondering if someone has found parallels for this pose - not just in gemini images, but the pose in general. I have a suspicion it may provide a key for the image.

Since it's a man and a woman, I'd start by looking into marriage rituals.

Edit: or is he holding her one hand and giving her something with the other?
