Gemini crossed arms imagery

[Davidsch]

Beth Alpha Gemini are in line with a relatively common form which has parallels in eastern and western manuscripts alike.

It has little to do with the VM crossed arms, which stem from images of courtly love scenes. 

It will have to be investigated further if this pose has a specific significance or whether it evoled from the ring-exchanging image Marco posted earlier.

@JKP, don't bother that angle. 
According to Koen, the decision on what it represent, has already been made.
