This is the prayer to the goddess Dike. I got this prayer from ‘In Praise of Olympus: In Praise to the Greek Gods’ by Hearthstone.

Firm-hearted Dike, sister of the Seasons, daughter of great Zeus and Themis of godly law, mistress of justice, friend of the wronged and the righteous; your strength lies in truth, goddess, in the worth of fair play, and in the rights of men.

O Dike, trusty one, the honorable one, the one whose word is ever good–these men and women find your favor, their prayers to you are answered well.

But those who lie, and cheat, and thieve, these evil-doers earn your wrath; never can they escape your vengeance.

Dike, whose sharp sword pierces the heart of the unjust, who protects the honest and the noble, the upright and the true, fair-minded goddess, impartial one, the rule of right is ever your concern.

Dike, champion of the good, I praise and honor you.
