DIÆTETÆ, in Grecian antiquity, a kind of judges, of which there were two sorts, the cleroti and diallaclerii. 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 diallaclerii, 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.
