Much of the revenue for the Hellenistic kingdoms was derived from agricultural products, rents paid by the tenants of royal land, and taxation of land. Trying to improve productivity, the rulers sponsored experiments on seed grain, selecting seeds that seemed the most hardy and productive. Egypt had a strong tradition of central authority dating back to the pharaohs, which the Ptolemies inherited and tightened. They had the power to mobilize local labor into the digging and maintenance of canals and ditches, and they even attempted to decree what crops Egyptian farmers would plant and what animals would be raised. Such centralized planning was difficult to enforce at the local level, however, especially because the officials appointed to do so switched positions frequently and concentrated most on extracting taxes. Thus, despite royal interest in agriculture and a more studied approach to it in the Hellenistic period, there is no evidence that agricultural productivity increased or that practices changed. Technology was applied to military needs, but not to those of food production.
Diodorus Siculus, a Greek historian who apparently visited Ptolemaic Egypt around 60 B.C.E., was surprised that Egyptians could feed all their children instead of resorting to the selective exposure of infants practiced in Greece. He decided that this was because of their less formal child-
They feed their children in a sort of happy-
Egyptian parents would probably have given other reasons, such as rents and taxes, for why their children had simple food and no shoes.
As with agriculture, although demand for goods increased during the Hellenistic period, no new techniques of production appear to have developed. Manual labor, not machinery, continued to turn out the raw materials and manufactured goods the Hellenistic world used. (See “Living in the Past: Farming in the Hellenistic World.”)
Diodorus gives a picture of this hard labor, commenting about life in the gold mines owned by the kings:
At the end of Egypt is a region bearing many mines and abundant gold, which is extracted with great pain and expense. . . .

Apart from gold and silver, which were used primarily for coins and jewelry, bronze continued to be used for shields. Iron was utilized for weapons and tools.
Pottery remained an important commodity, and most of it was produced locally. The coarse pottery used in the kitchen for plates and cups changed little. Fancier pots and bowls, decorated with a shiny black glaze, came into use during the Hellenistic period. This ware originated in Athens, but potters in other places began to imitate its style, heavily cutting into the Athenian market. In the second century B.C.E. a red-
