The prices of salt can be compared to present day as an analogy for electricity. Raising the price would not allow the lower classes to buy it. It allowed them to preserve food, and was also very important to eat enough salt for proper bodily functions. When there were no wars, the price would be set lower so everyone could once again buy it. In war times when money was scarce, the price would rise. The Roman Empire cared so much about the mineral that they took direct control over the prices it charged for the good. Salt was so important to the Romans that the network of roads that the Romans were famous for were built for the transportation of salt. Salt ponds were formed in the bordering regions of the Adriatic so that the salt could be formed and then transported to Rome. The Adriatic was good for salt because it was shallow, so the concentration of salt is higher.

In Rome, there access to salt was the Adriatic sea. In antiquity a lot of the salt came from the sea.
