First, what role of the Moon in science?
The moon is commonly known as a huge solar refraction/diffusion system, as well as a regulator of the earth’s tides and saps. What is less known is that the earth has always been sent to the moon a kind of ‘breath of life, ie a wind of charged particles of oxygen. The earth’s oxygen particles reach the moon when our planet, for 5 days every 27 days, comes between the Sun and the Moon, shielding the latter from the wind of particles emitted by our star (the solar wind). During this period, the solar wind is deflected and the particles trapped in most of Earth’s outer regions can reach the moon.
What role of the Moon in Alchemy?
Some ancient authors say that Moon at night makes the Spiritus Mundi which in daytime lingers at great altitudes ( because of the Sun raising power and for the effect of the magnetic field that acts as a screen) fall down to earth. Secondly, the moon may dismember in a most effective way than the sun. Third, the moon acts on the part of Spiritus Mundi which is known to behave like a fluid. So the composition of the air is decisive when working the Mercurius.
Without necessarily wanting to compare Spiritus Mundi and the etheric or subtle body that surrounds and interpenetrates all bodies, the laboratory alchemist must however admit that they behave in a similar way. Hekate, the mysterious three-headed goddess ubiquitous in heaven, earth, and the underworld, is symbolically represented by the moon.
Can we extract and/or condense the Spiritus Mundi from the Moon?
As we cannot extract and/or condense Spiritus Mundi directly from the Sun, we also cannot extract it directly from the Moon. Nevertheless, in the same way, the lunar beams can strike and so affect the surrounding airborne and watery particles, and produce chemical reactions which may improve these matters’ magnetization, allowing the Spiritus Mundi to come out. When the medieval alchemists claimed to gather the lunar beams, in form of a liquid, they instead gathered the airborne, aerosol, and water particles with improved magnetization.
What atmospheric chemical compounds are more likely to undergo reactions when affected by moonlight?
Nitrogen compounds, same as for the sunlight. And in addition all aerosol and watery particles. But moonlight would affect compounds and cause reactions mildly and differently than sunlight.
Does the moon have its own specific strength?
Yes, apart from the lunar phases involved in the astronomical code, the moon has its own specific strength when it is closest to the earth and then in its moment of greatest influence on the tides and terrestrial waters. And accordingly on the part of Spiritus Mundi which tends to behave like a fluid.
As regards the phases of the moon in alchemical works, there are dedicated faqs in Alchemical Timing & Astronomical Code.
