The Holy Roman Emperor Rudolf II (1552-1612) was an avid collector of art and a devotee of alchemy. When he relocated the Hapsburg court from Vienna to Prague he attracted many talents both scientific and artistic, including the Elizabethan mathematician John Dee, the astronomers Tycho Brahe and Johannes Kepler and skilled painters such as Bartholomeus Spranger, Adrian de Vries and Giuseppe Archimboldo.
Among the most original of artists at Rudolf II's court was the Milan-born Giuseppe Archimboldo (1527-1593). Rudolph II commissioned Archimboldo to paint what are probably his best-known works, a series of Four Seasons using his 'double meaning' technique. Archimboldo even applied his 'double meaning' technique to a portrait of his patron, painting the Holy Roman Emperor as Autumn, rich with the abundance of the fruits of the harvest (Above). Often afflicted with profound depression, the solitary-inclined Rudolf must have had a strange but confident perception of himself to allow such an experimental portrait. Archimboldo's 'double meaning' technique was imitated centuries later by Surrealist artists, notably by Salvador Dali.
Although nowadays Emperor Rudolf II is credited as being a major patron of the arts, in particular of Northern Mannerist art (one suspects that the four intriguing statuettes of the Layer Monument with their hidden esoteric symbolism would have appealed to Rudolf's taste) it's also been argued that his life-long collecting of art combined with his complete disinterest in politics and diplomacy contributed towards the collapse of the Holy Roman Empire and European political instability during the thirty years war (1618 -1648). A more positive interpretation of Rudolf II views him a major sponsor of the scientific revolution and an aspirant towards a united, polemic-free Europe.
Rudolf II also kept a menagerie of exotic animals, cultivated a botanical garden and collected a variety of curio's in what was to become Europe's most extensive 'cabinet of curiosities' or Kunstkammer. Rudolf's primary preoccupation however was the fabled philosophers stone of alchemy and he commissioned both scholars and alchemists in his quest. Foremost among scholars at the Prague court were the Paracelsian physician-alchemists Martin Rulands, the name of both father and son. Martin Ruland the elder (1532 -1602 ) compiled a dictionary of alchemical terminology, primarily orientated towards a Paracelsian and metallurgic nature. It must have been held in high esteem by Emperor Rudolf for he conferred the status of nobility upon Martin Ruland junior (1569-1611) in 1608. Martin Ruland's definition of meditatio is a good example of how devout Hermetic philosophers such as John Dee and Sir Thomas Browne augmented their Christian spirituality.
MEDITATIO - The name of an Internal Talk of one person with another who is invisible, as in the invocation of the Deity, or communion with one's self, or with one's good angel.
In Religio Medici (1643) Browne declared -
Therefore I am so far from denying their existence, that I could easily believe, that not only whole Countries, but particular persons have their Tutelary, and Guardian Angels: It is not a new opinion of the Church of Rome, but an old one of Pythagoras and Plato; - R.M. Part 1:33
Incontrovertible evidence that Browne consulted Ruland's dictionary can be found in his allusion to Ruland's entry -
QUANDROS - a Stone or Jewel which is found in the brain and head of the Vulture, and is said to be a bright white colour. It fills the breasts with milk, and is said to be a safeguard against dangerous accidents.
In Museum Clausum, Browne's bizarre inventory of lost, imagined and rumoured books, pictures and objects there can be found -
A noble Quandros or Stone taken out of a Vulture's Head.Although I've written on this before there's now the possibility of offering a link to the complete text of Rulands Dictionary of Alchemy.
