A version of relationism that takes spatiotemporal structures-spatial geometry and a standard of inertia-to supervene on the history of relations between bodies is described and defended.

Description
Summary:A version of relationism that takes spatiotemporal structures-spatial geometry and a standard of inertia-to supervene on the history of relations between bodies is described and defended. The account is used to explain how the relationist should con- strue models of Newtonian mechanics in which absolute acceleration manifestly does not supervene on the relations; Ptolemaic and Copernican models for example. The account introduces a new way in which a Lewis-style 'best system' might capture regularities in a broadly Humean world; a defence is given against a charge of indeterminism that applies to any such approach to laws.
