Tuareg crosses (Croix du sud) come in different shapes and motifs and they are named after oasis towns in Niger. They are passed down from father to son when the boy reached puberty. He says to his son that he has given him the four corners of the world where one would not know where one would end up. This powerful amulets can also be converted as a form of currency in times of need to buy cattle, clothing or food. The Agadez cross is best known of all crosses. The engraving of a round circle in the centre represents the eye of a chameleon which is symbolic of power and the jackal tracks along the four sides is symbolic of craftiness.
