that the term poleis, according to Spek, did not confer any special status to cities in the Seleucid sources; it was simply the term for "city"—Greek or otherwise. Regardless, agricultural produce varied from region to region. But in general, Greek poleis produced: "grain, olives and their oil, wine…figs, cheese from sheep and goats, [and] meat." Whereas Mesopotamian production from temple land consisted of: "barley, dates, mustard (or cascuta/dodder), cress (cardamom), sesame and wool"; which, as the core region of the Seleucid empire, was also the most productive. Recent evidence indicates that Mesopotamian grain production, under the Seleucids, was subject to market forces of supply and demand. Traditional "primitivist" narratives of the ancient economy argue that it was "marketless"; however, the Babylonian astronomical diaries show a high degree of market integration of barley and date prices—to name a few—in Seleucid Babylonia. Prices exceeding 370g silver per ton in Seleucid Mesopotamia was considered a sign of famine. Therefore, during periods of war, heavy taxation, and crop failure, prices increase drastically. In an extreme example, Spek believes tribal Arab raiding into Babylonia caused barley prices to skyrocket to a whopping 1493g silver per ton from 5–8 May, 124 BC. The average Mesopotamian peasant, if working for a wage at a temple, would receive 1 shekel; it "was a reasonable monthly wage for which one could buy one kor of grain= 180 [liters]." While this appears dire, we should be reminded that Mesopotamia under the Seleucids was largely stable and prices remained low. With encouraged Greek colonization and land reclamation increasing the supply of grain production, however, the question of whether this artificially kept prices stable is uncertain. The Seleucids also continued the tradition of actively maintaining the Mesopotamian waterways. As the greatest source of state income, the Seleucid kings actively managed the irrigation, reclamation, and population of Mesopotamia. In fact, canals were often dug by royal decrees, to which "some were called the King's Canal for that reason." For example, the construction of the Pallacottas canal was able to control the water level of the Euphrates which, as Arrian notes in his Anabasis 7.21.5, required: "over two months of work by more than 10,000 Assyrians." Role of the state—political economy As a hegemonic empire, the state's primary focus was maintaining its sizable army via wealth extraction from three major sources: tribute from autonomous poleis and temples, and proportional land-tax from royal land.
