The axioms before Peano

A subject the papers are about. The loosest grouping, and the one to reach for last.

Where the Peano axioms came from. Collects the nineteenth-century originals the standard account names -- Grassmann, Frege, Dedekind, Peano -- in the language each was written in, with the notation sources they depend on. The set is a priority dispute, so membership requires the original text rather than a later exposition.
