Ἐλευθέριος

Zeus was called [this] for this reason, because freedmen [eleutheroi] built the portico near him.¹ So [says] Hyperides.² But Didymus maintains that it is not because of this, but because of the fact that the Athenians escaped subjection to the power of Persia.³
Some interpret "of Freedom" [e)leuqe/rios] as "licentious" [a)/swtos]; and see under 'mastery'.⁴
