Salt was not seasoning—it was survival, the mineral that preserved meat through winter, the substance that maintained human health, the commodity valuable enough to wage wars over, the white crystals that meant the difference between starvation and abundance. Without salt, meat rotted within days. With salt, it lasted months. The household with adequate salt survived winter. The household without it watched helplessly as precious meat spoiled, the year’s protein supply becoming inedible waste.
Celtic peoples obtained salt through multiple methods—evaporating seawater, mining rock salt, collecting from natural springs. Each method required specialized knowledge, substantial labor, and access to specific resources. Salt production was not casual activity but serious undertaking, often controlled by those wealthy enough to invest in the necessary infrastructure.
And salt carried weight beyond its practical uses—it was trade commodity, wealth-store, ritual substance. Salt preserved not just food but also agreements (salt covenant), marked hospitality (sharing salt and bread), and possessed spiritual properties that made it protection against evil, purification agent, and offering to gods.
