Quicksilver and Mercury By Nick Kollerstrom Back to Metal-Planet Affinities index page Mercury appears sometimes in the form of a fluid metal, sometimes in the form of a hard brittle metal, sometimes in the form of a corrosive pellucid salt call'd Sublimate, sometimes in the form of a tasteless, pellucid white Earth, call'd Mercurius dulcis, or in that of a red opake volatile Earth, call'd Cinnabar; or in that of a red or white Precipitate, or in that of a fluid Salt; and in distillation it turns into a Vapour, and being agitated in vacuo, it shines like Fire. And after all these Changes it returns again into its first form of Mercury.' Sir Isaac Newton (1) 'A mind like quicksilver'-how well this image applies to mental processes! It is hardly surprising that astrologers should associate the planet Mercury with mental agility: the shining globules of this liquid metal form and reform so quickly, as fast as thinking. The metal mercury is the one element that one normally sees in the three states of matter - as the fluorescent lamp overhead in the classroom, as the liquid in the thermometer and as calamine the skin lotion; as Hermes was the one deity who could come and go through the three worlds. Alas, the nimble quicksilver intelligence can end up as the ‘mad hatter,’ whose mind is a-jumping all over the place - remembered in Alice’s immortal tea-party. This was a condition to which hatters were prone in Victorian times, due to using mercury metal to give a shine to top hats.  As Hermes was the messenger of the gods, so mercurial types make good link people. Likewise the metal mercury amalgamates: different metals can be brought together by dissolving them in mercury, it is a solvent for metals. The term 'amalgamate' is also used in commerce: different firms amalgamate together. This is a mercury-process, and Hermes was traditionally the god of commerce. Mercurius in the Air Famae alchymine, Leipzig 1717 The most characteristic chemical trait of mercury is association. It links itself up in the most unexpected ways. The tendency to form complex compounds is very marked in the case of mercury.(2) It combines with nitrogen and carbon compounds which metals normally won't touch, as well as forming the usual metal salts, and forms complicated 'organometallic' mercury compounds, which catalyse the synthesis of a range of pharmaceutical and other organic, man-made products. It forms explosives (e.g. mercury iodide) which detonate at a mere touch. In amalgamating other metals together, it performs this interlinking function. The Indian word for alchemy was ‘Rassayana’ which means ‘the way of mercury.’ The earliest alchemical texts in the West date from the first century AD, and this is also when the first texts for obtaining mercury from its ore cinnabar appear. Pliny the Roman naturalist gave such a recipe. Heating of the red ore cinnabar causes it to sweat globules of the shining metal; then, careful heating the mercury again yield a red ore (although this is the oxide, no longer the sulphide). This was the classic recipe whereby alchemists impressed their clients, and was the first inkling of a chemical reaction. Mercury’s changeable nature seemed to manifest mysteries of matter. Hermes in his Egyptian form as ‘thrice-greatest’ was the patron of alchemy, in which mercury had the central role. Alchemists who reckoned they could make gold would usually start off with mercury (which is, as chance would have it, next to gold in the Periodic table) Mercurius in water The orbit of this fastest-moving of planets was an enigma for a century. The plane of Mercury's orbit kept 'precessing' or shifting about in a way that defied explanation, and Newton’s theory could not account for it. Mercury resisted this materialistic world conception, and it was only explained in the 20th century by the Theory of Relativity. Likewise, the metal mercury resists the solid state. It is the secret, the mystery of quicksilver, that a metal of such enormous density can yet remain liquid. It is not difficult to see why the alchemists credited mercury with a very special inner mobility and vitality. Ancient Indian texts tell of ‘Vimana’ which were fabulous flying craft (e.g. in the Mahabarata). These texts inform us that the craft were powered by mercury. Clearly, speedy mercury was just the stuff to power these mythic ancient craft! The commonest daily use for mercury sees it in constant motion - the thermometer. Hermes was traditionally the god of medicine, and Mercury was for long given an important role in medical practice. It was for centuries the staple remedy for syphilis, and even today it is still used for skin ointments-calomel-and the sublimate is used as a disinfectant. Mercury amalgams are used in dentistry, and mercurial aids such as the thermometer and blood pressure apparatus aid the doctor. Thus the different aspects of the Mercury-nature are expressed both by the metal and by the planet in the sly, in accordance with the Hermetic maxim, 'as above, so below.' |
