All-seeing Zeus

I will sing of Zeus,...

...chiefest among the gods and greatest, all-seeing, the lord of all, the fulfiller who whispers words of wisdom to Themis as she sits leaning towards him. Be gracious, all-seeing Son of Cronos, most excellent and great! Homeric Hymns XXIII

Muses of Pieria who give glory through song,...

...come hither, tell of Zeus your father and chant his praise. Through him mortal men are famed or un-famed, sung or unsung alike, as great Zeus wills. For easily he makes strong, and easily he brings the strong man low; easily he humbles the proud and raises the obscure, and easily he straightens the crooked and blasts the proud, -- Zeus who thunders aloft and has his dwelling most high. Hesiod - Works and Days
