Chemical Analyses Find Hidden Elements From Renaissance Astronomer Tycho Brahe’s Alchemy Laboratory 

"In the Middle Ages, alchemists were notoriously secretive and didn’t share their knowledge with others. Danish Tycho Brahe was no exception. Consequently, we don’t know precisely what he did in the alchemical laboratory located beneath his combined residence and observatory, Uraniborg, on the now Swedish island of Ven. Only a few of his alchemical recipes have survived, and today, there are very few remnants of his laboratory. Uraniborg was demolished after his death in 1601, and the building materials were scattered for reuse."

By Peter Maxwell Davies.

"The title refers to the alchemical process of ‘whitening’ ‘by which a base metal may be transformed into gold, and by extension, to the purification of the human soul.’ This is an interesting piece, which uses the magic square of mercury as its most fundamental compositional structure."

"In an address to Maximilian II, which prefaces his Monas Hieroglyphica (1564), John Dee emphasises that the Monad is not only an alchemical device, but a universal one, with the potential to revolutionise all the arts and sciences. Amongst the examples given are applications to geography, astronomy and music, of which Dee writes:

“How justly may the musician be struck with wonder when here he will perceive inexplicable, celestial harmonies without any movement and sound.” (Josten 1964, 130-1)."

"This work is based on the three times three 'stages' of mediaeval alchemy. There is nothing arcane about this: for musical composition is of its nature an 'alchemical' transformation of something (pitch relationships, rhythms, metres, harmonies, timbres) into something else; and Jung has demonstrated that the metamorphoses of alchemy are, like those of music, not so much material as psychological." - Wilfrid Mellers
