Four half-men awkwardly holding hands inside four concentric bands.

[Koen G]

So the joining of hands, as Marco explains, means the sharing of a property. If the VM diagram is somehow based on Bede or something similar and uses the same visual vocabulary, what does that mean?

In Bede you get a nice linking-and-opposition scheme. But in the VM it's much less clear what the connection between the four figures is supposed to be. Still, there appears to be an awareness that the figures could connect, almost like an allusion to the Bede scheme. Left and Right are looking at Bottom. Left is reaching for bottom, while Bottom is reaching for Left and Right. Right is lifting his ball. Bottom appears to be looking at left? Top is reaching for Left and Right, but does not get any attention back. Top is looking at Left? 

   

The "reaching figure peaking over the horizon" returns in the two-birds page, where similarly the figures in the four corners are reaching/looking at each other.
