The 7 terrestrial and celestial metals are symbolized by 7 figures = Muses sitting in the cave or cavern. Between night and day, the 7 planets are in continuous rotation between 4 Elements. Three figures = Sulphur = fire, Star of David = The Stone and Mercury = Water. In the image we can recognize the Salamander = Fire. Three angels = Wind. The boat or ship = Water. And the landscape = Earth. It is the union of the low and the high =''as above, so below'' in clear ideological affiliation with the Emerald Tablet. In the lower part the 6 Muses=metals surround Apollo, with his Lyre= {music of the spheres}, in the depths of the alchemical underworld=Interior Visit to Terrae, Rectifying invenies occultam lapidem. In the center above two intertwined Triangles or the six-pointed Star of David and Solomon's Alchemical Seal combines 2 Triangles in clear symbolic fusion. The motto in translation from Latin: 'The things that are in the realms above are also in the realms beneath; What heaven shews is often found on earth. Fire and flowing water are contrary one to other; Happy thou, if thou canst united them: let it suffice thee to know this!' It is the alchemical symbolism of 'prima materia' and symbol of Wisdom.
