This article examines the definitions of place or location (topos) and as a consequence, space, in Byzantine philosophy, from Maximos the Confessor to Photios. These philosophers draw, on one hand, on the Aristotelian, Platonic, and Neoplatonic sources, and on the other hand, on the Judeo-Christian tradition. Firstly, Maximos the Confessor sets out a novel definition in which place is conceptually inseparable from time, is needed for substances to exist, and in which place is the boundary between the created and uncreated. (...) In Anastasios of Sinai’s writing, God is the archetypical place for all things and is likewise necessary for substances. John of Damascus, in contrast, extends Aristotle’s definition of place in the Physics in new directions, by investigating the place of angels, which is determined by their incorporeal limits. Finally, Photios produces a systematic and astute account of how the properties of the containing and contained bodies come together to make places. The article concludes with an evaluation of these theories, and briefly considers their relationship to theories of place and location in modern physics. (shrink)
