Ring of Planets

Dennis William Hauck wrote an Interpretation of artist Matthieu Merian's 1618 Tabula Smaragdina (Emerald Tablet) engraving which contains a few yellow Hexagrams:

The first area encountered as the alchemist travels along this vertical axis is a Ring of Stars in which seven larger stars predominate. This stellar ring presents the seven alchemical operations as cosmic principles available to sentient species everywhere... To the left of the large triangle is a smaller downward-pointing triangle representing Water or Mercury; to the right is a small upward-pointing triangle representing Fire or Sulfur. Below the central triangle is the Star of David, which symbolizes Salt, the union of Fire and Water, the permanent coming together of the Above and the Below.
