C.G. Jung identified the 17th century as the era of alchemy's last and greatest flowering. And indeed, many noble flowers from the garden of alchemy including lavishly illustrated art-works, ornate in their imagery, accompanied by extraordinary dense texts which elaborate upon 'Celestial Agriculture', germinated and bloomed during the 17th century.
It was also during the 17th century that the slow, but decisive, fissure and schism between Science and Faith opened up; the new man-made truths in astronomy, anatomy and physics unearthed by the enquirers and advocates of the 'New Learning', embryonic scientists no less, eventually challenged and competed for dominance in intellectual supremacy over the God-given Cosmology and the eternal truths of Christianity.
The 17th century, often described as the last great age of religious Faith and private devotion, was an era of specific interest to C.G. Jung. According to the Swiss physician in his autobiography Memories, Dreams, Reflections, his many years study of alchemy were inaugurated by a dream in which he visited a large Ducal Palace situated somewhere in Northern Italy. While exploring the palace's vast chambers, he heard in his dream, its heavy doors slamming shut. Jung interpreted his portentous dream as signifying he was now 'trapped' in the 17th century, his confinement signified he believed, a long study of alchemical literature originating from the baroque century, until somehow set free.
C.G.Jung recognised that the single profession which engaged in the art of alchemy were physicians. These alchemist-physicians, invariably of a Protestant background, many of German or English background were often cautiously sympathetic to the new 'chemical' medicine of Paracelsus. They used distinctly apt symbols closely related to their profession, notably from anatomy, optics and astronomy to discourse upon their sometimes unorthodox, and even near-heretical, spiritually-orientated studies.
Included among the treasures of seventeenth century alchemical art are a series of illustrations rich in symbolism entitled Philosophia reformata (1622) by the German author Johann Daniel Mylius (c.1535-1642) who wrote on medicine and alchemy. Emblem 9 in Mylius's sequence of 28 illustrations is entitled Putrefactio (above). It is described thus - 'On the top of a flaming black globe stands a skeleton holding a black crow in its right hand. On each side of him there is a winged angel, both of which point to the black globe. In the heavens above, the Sun and the Moon are visible. In the lower foreground can be seen a regenerating tree stump'.
The skeleton and the skull are frequently encountered in Christian and alchemical art symbolism. They retain a vestige of their numinous content as reminders of mortality and Death.
A belief in angels was once a vital entity of spiritual belief. Many people, educated and illiterate, throughout 17th century Europe fervently believed in both angel and witchcraft. Angel's roles include that of musician and psychopomp, most often they are depicted as celestial messengers.
The Rotundum is a symbol frequently encountered in alchemical imagery, as are the crowded perches and aviaries associated with bird symbolism in alchemy; a feathered assembly of swans, ostriches, doves, eagles, vultures and pelicans flock the pages of alchemical art. The blackbird, crow and raven are each associated with the Nigredeo stage as is the operation of Putrefactio, along with the variant stages of Mortificato and Calcinato.
Whether Thomas Browne as a young medical student studying abroad circa 1627-1630 ever perused the books of the German alchemist-physician J.D. Mylius isn't known, nor is there any recorded evidence of J.D. Mylius's books being listed in the 1711 Sales Auction catalogue of Browne's library. However, several decades after completing his three years medical study on mainland Europe, Browne made what is credited as his single scientific discovery. Its a discovery utterly characteristic of his era, when human life was often precarious and short for many from the ravages of Civil War, plague and disease and utterly compatible to the dark Nigredo contemplations of Urn-Burial.
Browne augments his solemn funerary threnody adding to the heaped pyre of images and symbols, a short, but detailed description of his medico-scientific discovery. His observation on the effects of Putreficato and the formation of the waxy substance which coagulates upon body fat, known as adipocere, can be found in chapter 3 of Urn-Burial, a work which has been described as 'reeking of the Grave'.
In a Hydropicall body ten years buried in a Church-yard, we met with a fat concretion, where the nitre of the Earth, and the salt and lixivious liquor of the body, had coagulated large lumps of fat, into the consistence of the hardest castile-soap: wherof part remaineth with us.
More than one scientific observation can be found in Urn-Burial along with several archaeological hypotheses, there is even a far-sighted prediction of future forensic science in the proposal that - 'Physiognomy outlives our lives, and ends not in our graves.'
Upon more than one occasion the Norwich-based early scientist concludes his observations with the remark, 'whereof part remaineth with us'!
