DIETETÆ, in Grecian antiquity, a kind of judges, of which there were two ſorts, the cleroti and diallaſterii. The former were public arbitrators, choſen by lot to determine all cauſes exceeding ten drachms, within their own tribe, and from their ſentence an appeal lay to the ſuperior courts.
The diallaſterii, on the contrary, were private arbitrators, from whose ſentence there lay no appeal, and accordingly they always took an oath to adminiſter juſtice without partiality.
