cultivated by 2500 BCE on Crete, and possibly in mainland Greece too. That the vine was introduced, rather than having always been present, was acknowledged in later Greek myths, according to which the gods drank nectar (presumably mead), and wine was introduced later for human consumption. Grapevines were grown alongside olives, wheat, and barley and were often intertwined with olive or fig trees. In the Mycenaean and Minoan cultures of the second millennium BCE, on the Greek mainland and on Crete, respectively, wine remained an elite drink, however. It is not listed in ration tablets for slave workers or lower-ranking religious officials. Access to wine was a mark of status.
The reigns of Ashurnasirpal and his son, Shalmaneser, there fore marked a turning point. Wine came to be seen as a social as well as a religious beverage and started to become increasingly fashionable throughout the Near East and the eastern Mediterranean. And its availability grew in two senses. First, wine production increased, as did the volume of wine being traded by sea, making wine available over a larger geographic area. The establishment of ever-larger states and empires boosted the availability of wine, for the fewer borders there were to cross, the fewer taxes and tolls there were to pay, and the cheaper it was to transport wine over long distances. The luckiest rulers, like the Assyrian kings, had empires that encompassed wine-making regions. Second, as volumes grew and prices fell, wine became accessible to a broader segment of society. The growing availability of wine is evident in the records that list the tribute presented to the Assyrian court. During the reigns of Ashurnasirpal and Shalmaneser, wine began to be mentioned as a desirable tribute offering, along with gold, silver, horses, cattle, and other valuable items. But two centuries later it had vanished from the tribute lists, because it had become so widespread, at least in Assyria, that it was no longer deemed expensive or exotic enough for use as an offering.
Cuneiform tablets from Nimrud dating from around 785 BCE show that by that time wine rations were being provided to as many as six thousand people in the Assyrian royal household. Ten men were allocated one qa of wine per day to share between them; this amount is thought to have been about one liter, so each man would have received roughly one modern glass of wine per day. Skilled workers got more, with one qa being divided between six of them. But everyone in the household, from the highest officials to the lowliest shepherd boys and assistant cooks, was granted a ration.
As the enthusiasm for wine spread south into Mesopotamia, where local production was impractical, the wine trade along the Euphrates and Tigris rivers expanded. Given its heavy and perishable nature, wine was difficult to transport over land. Long-distance trade was done over water, using rafts or boats made of wood and reeds. The Greek historian Herodotus, who visited the region around 430 BCE, described the boats used to carry goods by river to Babylon and noted that "their chief freight is wine." Herodotus explained that once they had arrived downstream and had been unloaded, the boats were nearly worthless, given the difficulty of transporting them back upstream. Instead, they were broken up and sold, though typically only for a tenth of their original value. This cost was reflected in the high price of the wine.
So though wine became more fashionable in Mesopotamian society, it never became widely affordable outside wine-producing areas. The prohibitive cost for most people is shown by the boast made by Nabonidus, the last ruler of the Neo-Babylonian Empire before it fell to the Persians in 539 BCE. Nabonidus bragged that wine, which he referred to as "the excellent 'beer' of the mountains, of which my country has none," had become so abundant during his reign that an imported jar containing eighteen sila (about eighteen liters, or twenty-four
