 Pheidon is also thought to have introduced reforms for standard weight and measures in Argos, a theory further reinforced with the unearthing of six "spits" of iron in an Argive Heraion, possibly remainders of a dedication from Pheidon.In 494 BC, Argos suffered a crushing defeat at the hands of its regional rival, Sparta, at the Battle of Sepeia.Following this defeat, Herodotus tells us the city suffered a form of "stasis".
