Zaleusus flourished as king of the ancient Greek Locrians in about 500 B.C. His government over the Locrians was severe but just. In one of his decrees he forbade the use of wine unless it were prescribed as medicine; and in another he ordered that all adulterers should be punished with the loss of both their eyes.
When his own son became subject to this penalty, the father, in order to maintain the authority of the laws, but to show parental leniency, shared the penalty with his son by ordering one of his own eyes to be thrust out along with one of his offending son. In this way, the majesty of his government was maintained, and his own character as a just and righteous sovereign was magnified in the eyes of his subjects.
