QUOTE : With the decline of Italian agriculture and the provision of subsidized corn for the urban masses in the capital, Sicily was Rome’s most important provider of cereals and it was essential to ensure stability of its supply and price. The oldest of Rome’s provinces, the island had been won from the Carthaginians in 241 and, as tribute, its communities were required to export gratis 10 percent of their corn harvest to Rome. If more was needed, it could be acquired by compulsory purchase. It was the Quaestors’ job to calculate the price and the quantity of extra corn to be bought.
