Zaleucus, the lawgiver of the Greek colony Locri Epizephyrii in the 7th Century B.C., found himself called upon to give judgement on his son, accused of adultery, for which the punishment was blinding in both eyes. The verdict was guilty. The citizens, out of regard for the father wished to revoke the penalty, but Zaleucus, determined to satisfy his own laws, had one of his son's eyes plucked out and one of his own.

The attribution was suggested by Professor Werner Sumowski in a letter dated 3 February 1993.
