Christoph Cellarius

Christoph Keller Cellarius 22 November 1638 – 4 June 1707 was a German classical scholar from Schmalkalden who held positions in Weimar together with Halle. Although the Ancient-Medieval-Modern division of history was used earlier by Italian Renaissance scholars Leonardo Bruni as alive as Flavio Biondo, Cellarius' Universal History divided up up into an Ancient, Medieval, in addition to New Period helped popularize it. After him, this tripartite division became standard.
