The best evidence to support the statement that Roman soldiers weren't always paid with money is: "In early times they might have been provided with salt, which was a valuable commodity. The word salary comes from sal, the Latin word for "salt." The word soldier, in turn, comes from an old French word for "salary,"" from the passage provided. This suggests that soldiers were not always paid with traditional currency and that other valuable commodities, such as salt, may have been used as payment.
