Jupiter

...

In medieval geomantic illustrations, the constellations (and other celestial objects) are represented/symbolized with dots that look like the patterns on domino bricks and several of them use seven dots arranged in different ways. The number seven is certainly not limited to Pleiades.

This is not true.

In You are not allowed to view links. Register or Login to view.SOMETIMES the constellations are used, however most of the time there is another basis for the geomantic figures. 
It is also an misunderstanding that these are always dots. That is not true. Dots appear quite often, but it can also be a pen stroke, an illustration, grains, sand etc.

In my experience, it occurs quite often that libraries are unaware that they have books on geomancy.
