The Medimnos: A Unit of Volume
Definition and Primary Use
The medimnos (Ancient Greek: ฮผฮญฮดฮนฮผฮฝฮฟฯ, mรฉdimnos) was a significant unit of volume within the Ancient Greek system of measurement. Its primary application was in quantifying dry commodities, most notably food grains, which formed the bedrock of ancient economies and sustenance.[1]
Regional Variations in Volume
While serving a common purpose, the precise volume of a medimnos was subject to considerable regional variation across the Hellenic world. In the influential region of Attica, a medimnos was standardized at approximately 51.84 litres. However, other city-states employed different calibrations; for instance, the Spartan medimnos was notably larger, approximating 71.16 litres.[2][3]
Subdivisions and Smaller Measures
The medimnos was not merely a standalone unit but also served as a basis for smaller, fractional measures, facilitating finer transactions and allocations. These subdivisions included:
- Tritaios: One-third of a medimnos.
- Hekteus: One-sixth of a medimnos.
- Hemiektos: One-twelfth of a medimnos.
- Choinix: One-forty-eighth of a medimnos.
- Kotyle: A smaller unit, approximately 0.27 litres, representing a fraction of the medimnos (its exact fractional value varied with reforms).[4]
Historical Context and Adoption
Origins and Spread
The medimnos unit is believed to have originated in the influential city-state of Corinth. From Corinth, its utility and standardization led to its adoption by other prominent Greek poleis (city-states), including Classical Athens and Megara, becoming a widely recognized measure across the Hellenic world.[5]
Solon's Timocratic Constitution
The medimnos played a pivotal role in the socio-political reforms enacted by Solon in Athens around 595 BCE. His establishment of a Timocratic Constitution utilized the medimnos as a basis for taxation and social stratification. Citizens were required to pay specific quantities of grain as tax to attain certain ranks or social statuses. For example, a substantial payment of 500 medimnoi was necessary to qualify for the rank of military commander, whereas a lesser amount, 200 medimnoi or fewer, sufficed for an agricultural worker.[5]
Later Reforms and Weight Estimation
Second Century BCE Adjustments
Significant adjustments to the medimnos occurred in the second century BCE. Following these reforms, the standard volume of the medimnos was recalibrated to 58.92 litres. Concurrently, most of its smaller subdivisions retained their proportional values, with the notable exception of the kotyle, which was redefined to represent 1/238 of the revised medimnos.[3]
Estimating Weight
Determining the precise weight of a medimnos is challenging due to variations in commodity density. Current scholarly estimations suggest that a medimnos of wheat would weigh approximately 40 kilograms. For barley, a less dense grain, the estimated weight is around 31 kilograms. These figures are vital for understanding the logistical and economic implications of tribute and trade.[5]
Consumption and Societal Scale
Annual Sustenance Needs
Estimates suggest that an active adult male in sixth-century BCE Athens required approximately eight medimnoi of grain annually for sustenance. A typical female would consume a slightly lesser amount. Extrapolating from these figures, a young family unit, comprising a father, mother, and three children, would have collectively consumed roughly 25 medimnoi per year.[5]
Economic Implications of Rank
The substantial tax payments required for high social or political ranks underscore the scale of wealth and resource control in ancient Athens. The payment necessary to attain a very high rank could, by these estimations, sustain approximately 20 families annually. This highlights the medimnos not just as a measure of volume but as a proxy for economic power and social standing.[5]
Insights from Ancient Texts
Herodotus and Silver Tribute
The historian Herodotus records that during the reign of Xerxes II, the Satrap of Assyria, Tritantaechmes, received a daily income equivalent to just over one medimnos of silver. This amount is estimated to be approximately 55 litres, indicating the medimnos was also used metaphorically or as a benchmark for monetary wealth.[6]
Polybius and Military Rations
According to the historian Polybius, during the Punic Wars, Roman army rations were quantified using the medimnos. Infantrymen received two-thirds of an Attic medimnos of wheat monthly, while cavalry received seven medimnoi of barley and two of wheat. Allied forces had similar allocations, with cavalry receiving one and a third medimnoi of wheat and five medimnoi of barley.[7]
Josephus and Herod's Grain Distribution
The historian Josephus documents a period of drought during the reign of Herod the Great. To alleviate hardship, Herod petitioned the prefect of Egypt for grain. The distribution involved 10,000 cori of wheat (each corus being ten Attic medimnoi) for foreigners, and an additional 80,000 medimnoi distributed within Herod's own kingdom, illustrating the medimnos's role in large-scale state provisioning.[8]
Epiphanius and Roman Influence
Epiphanius of Salamis discussed the medimnos, suggesting its name might derive from the Roman word "medium" (middle). He noted variations in its usage, particularly in Cyprus, where the medimnos in Salamis equated to 5 modii, while in Paphos and Sicily, it was measured as 4ยฝ modii, indicating evolving interpretations and influences.[9]
