The medieval scholar Ahmad al-Tifasì in his Lapidary writes: “Coral is halfway between the world of plants and the mineral one. It resembles minerals because it is petrified and plants because it is a tree that grows at the bottom of the sea with roots and branches stretching upwards.” And again: Coral is said to possess other divine powers. In battle and among enemies it preserves the wearer unharmed, and for those who undertake a long journey in the desert it is a talisman that defends against all evil, and escapes from the dangers of bandits. Very powerful against all fears and snares of evil men and especially in journeys against the attacks of ill-intentioned people.
They say that it not only has the power to ward off drought, hailstorms and all things of this kind, but that it causes everyone to die rodents that consume and damage the crops, worms, woodworms, and other scourges of the air, locusts and locusts but also storms and lightning. Its therapeutic and superstitious virtues also make it a bringer of calm, healing, a heart tonic, excellent for blood circulation and as an antidepressant.
Bringer of abundance, fertility, longevity and good luck. Creature of the sea, it grows only in clear waters.”
