I was working on something else, but stumbled upon this detail. 

Looks like a gamecube or dice.

I know I saw it in the VMS somewhere, perhaps it was on the rosette, but I will be too distracted if I try to find it. 


Anybody recognizes it, and has knowledge on the function of this detail image? 

Perhaps a wind-direction-compass-like thing?



Ps. B2way, nice new postings here on the forum with some good progress on the house-buch.

Hi David, great to read you on the forum!

The text below the ship mentions Portugal and that die appears to be some form of a Portuguese flag or coat of arms.

These are what I would have expected to trigger familiarity, but it doesn't seem very conclusive. These kinds of designs are used in folk art from practically every culture.
