Through its focus on the question of circulation, world history attained a central position amongst the historical configurations in the last decade. Indicative of our fundamentally changing world, the past thereby reveals itself to have been shaped by commercial, human and intellectual flows of global dimension. The history of science has been particularly receptive to such methodological developments, especially with regard to works influenced by a markedly social approach to science and knowledge, which has focused for some time on the analysis of intellectual networks. From the French provincial Enlightenment to Athansius Kircher's circles—including the relationships of patronage of mathematicians and court philosophers—social, intellectual and epistemological configurations have been designed, allowing us to consider different scales in the circulation of knowledge.
