DĬĂDĒMA, originally a white fillet, used to encircle the head. It is
represented on the head of Dionysus, and was, in an ornamented form,
assumed by kings as an emblem of sovereignty.
DĬAETĒTAE (διαιτηταί), or arbitrators, at Athens, were of two kinds;
the one public and appointed by lot (κληρωτοί), the other private,
and chosen (αἱρετοί) by the parties who referred to them the decision
of a disputed point, instead of trying it before a court of justice;
the judgments of both, according to Aristotle, being founded on
equity rather than law. The number of public arbitrators seems to
have been 40, four for each tribe. Their jurisdiction was confined to
civil cases.
