Did you notice that odd drawing above the grasshopper? What could this be?

The image is right in the middle of the tracing board, so the symbol must be important.

Feddersen has three similar tracing boards. The image above is on the right of two pages. The one on the left has been drawn somewhat better.

He says that they are the same board, but the one on top has been hand coloured. This can obviously not be true. Just compare details. The sheep/lamb on the board on the top, looks more like a dog with a collar at the bottom. Besides, the sfinx has been turned, the skull below the grasshopper differs, as does the dove, there is a word “Westen” below the butterfly, etc.
Most strikingly, the thing in the middle is different too. The ‘beams’ (or whatever they are) are like rays of the sun in one drawing, and more like vegetation growing towards the East in the other. Also, the center of the image is not exactly the same.
These two are from “Scandinavia other” (SO), the also has an example from Denmark (SD) with again a small variation to the image in the middle.


Feddersen ascribes all tracing boards to the “Vertrauten Brüder St. Andreas” (‘trusted Brethern of St. Andrew’) and says that the tracing boards are no longer in use.
It appears that the “Vertrauten Brüder” is the VIth degree in the system of the Große Landesloge der Freimaurer von Deutschland (Grand National Lodge of the German Freemasons), a Swedish Rite variation with initially seven, later nine degree of which the first three are called “Johannesgraden” (‘St. John degrees’), then there are two “Andreasgraden” (‘St. Andrew’ degrees, sometimes called “Scottish”), four “Chapter Degrees” and honorary degrees.
I have not yet found rituals that might explain the drawing in the centre of this tracing board. As exotic as it looks, all other symbols are still in use in German Freemasonry even today, including the grasshopper and the butterfly. Therefor I have been scanning German (ritual) texts to see if I could find a clue about the central drawing.
In texts in the neighbourhood of the grasshopper I find references to candles and swords, but neither seems to make sense. Perhaps the fact that the protrusions are 12 in number is significant. Maybe a symbolism similar to this?
In the ‘better’ drawing there seems to be a word ascribed to the image in the middle. It is hard to make out, but the word ascribed to the moon is “Silber” (‘silver’), so my guess is that the word here is “Rot” (‘red’). Not that that explains much, but as in that triangle there are the three elements of Paracelcian alchemy (salt, sulphur and mercury), there may be an alchemical symbolism at play. What, in that context, could be the other three symbols in that inner triangle? A cross (Andreas cross), some sort of geometrical drawing in a sun and a sun. Also, if the inner triangle would be ‘entirely alchemical’, the grasshopper appears out of place.
Not yet resolved! Suggestions are welcome.
