Medimnos

A medimnos (Greek: μέδιμνος, médimnos, plural μέδιμνοι,médimnoi) was an Ancient Greek unit of volume, which was generally used to measure dry food grain. In Attica, it was approximately equal to 51.84 litres, although this volume was frequently subject to regional variation. For example, the Spartan medimnos was approximately equal to 71.16 litres. A medimnos could be divided into several smaller units: the tritaios (one third), the hekteus (one sixth), the hemiektos (one twelfth), the choinix (one forty-eighth) and the kotyle (0.27 l.)

The medimnos originated in Corinth and was adopted as a unit of measurement by Classical Athens and Megara as well as various other Greek poleis.

It was the measure used by Solon to establish a Timocratic Constitution in Athens around 495 BCE. According to this constitution, various amounts of grain needed to be paid as tax to secure certain ranks or social statuses (for example, a payment of 500 medimnoi to become a military commander, but only 200 or less to become an agricultural worker). Since taxes could be paid in any of the foodstuffs common at the time (agricultural crops, wine meat fish etc.), it was necessary to adjust the actual volume being paid according to its relative value at the time of payment.
