In the early eighteenth century, an eclectic group of artists and architects working primarily in London believed that they could improve the arts by placing their working practices on an unassailable mathematical footing. In this endeavour they were inspired by a concept of universal harmony, which held that the entire cosmos was organised by God according to the rules of arithmetic and geometry. This concept had ancient roots, being associated with the Greek philosopher Pythagoras, among others, but it assumed a new significance in Hanoverian Britain thanks to the work of antiquarians and natural philosophers such as Isaac Newton, whose scientific discoveries were hailed in terms of the recovery of lost knowledge.
