The physical distribution of foods throughout the Roman Empire varied by location and type of food. Some foods were shipped by boat and then distributed once they reached port. Others, specifically meat, were transported by land and brought into urban areas. Special regulations were put in place for the distribution of olive oil, as the Empire made contracts with olive oil producers all over the Mediterranean. Free daily distributions of olive oil were enacted by Emperor Severus during his reign from 192 to 211 CE. His distribution policy lasted for at least a few centuries, but scholars are unsure if the policy continued thereafter. Wine was not as freely distributed as olive oil, but was sold for a very low price starting around 300 CE.
