Agoranomoi, overseers of the *market, an office known in many Greek states. In Athens there were ten, five for the city and five for the *Piraeus. They kept order in the market, saw to the quality of goods, and collected market dues (Ath. pol. 51. 1); but at Athens there were separate measures magistrates (*metronomoi) responsible for weights and measures, and magistrates responsible for the corn trade.
