Solon - Eunomia.

These things my spirit bids me
teach the men of Athens:
that Dysnomia
brings countless evils for the city,
but Eunomia brings order
and makes everything proper,
by enfolding the unjust in fetters,
smoothing those things that are rough,
stopping greed,
sentencing hybris to obscurity
making the flowers of mischief to whither,

and straightening crooked judgments.
It calms the deeds of arrogance
and stops the bilious anger of harsh strife.
Under its control, all things are proper
and prudence reigns human affairs

Solon
