The symbolism of salt
Salt is essential for life. It symbolises taste, enables food to be conserved, and even mummifies bodies!
It purifies – the Bible mentions that Sodom and Gomorrah were purified with salt. Sinners are changed into pillars of salt, and we can ward off evil and deter unwanted strangers by spreading salt.
However, salt can also kill. It kills weeds, corrodes, dries up and can make water undrinkable. It is this duality that has always impressed man.
Those who didn’t have salt developed ever more inventive techniques to obtain or produce it.
