Cosmograph combines a 16th century cosmograph from Christopher Clavius’; In Sphaeram Ioannis de Sacro Bosco gilded in 24kt gold and a screen printed layer of an excerpt of T.J Hulls 19th century constellation map featured in The Orient Line. 
 
Christopher Clavius was a mathematician and astronomer who contributed to the Gregorian calendar and was a pioneer of a mathematical method and curriculum in a time where it was ridiculed by his peers. He did sexy things with decimal points in astronomy, accepted inherent problems with the wonky ptolemaic model of the solar system and was a contemporary of Copernicus. 
A pretty cool guy all round.
