Worth Your Salt

When we say someone is "worth their salt," we usually mean they are competent at their work. But the phrase has an interesting history. According to NPR: "In Roman times, and throughout the Middle Ages, salt was a valuable commodity, also referred to as "white gold." This high demand for salt was due to its important use in preserving food, especially meat and fish. Being so valuable, soldiers in the Roman army were sometimes paid with salt instead of money. Their monthly allowance was called 'salarium' ("sal" being the Latin word for salt). This Latin root can be recognized in the French word "salaire" — and it eventually made it into the English language as the word 'salary.'"

Mithridates VI famously ingested small doses of poison to build up his immunity, but according to Pliny, the recipe called for other ingredients, too: dried nuts, figs, and rue leaves. Everything should be minced together and taken after having added a grain of salt: addito salis grano."

Spilling salt has been considered bad luck, to the point that Leonardo da Vinci in "The Last Supper" portrays Judas as having overturned a salt shaker.
