Mataki, or Mati (Μάτι as known in Greek) can be traced back to Ancient Greece. In most regions in Greece, there is still the strong belief that having a mati causes supernatural power to protect the person who wears one, from evil thoughts and actions of others to them. They are not found just in Greek tradition. There is a widely extended belief of their supernatural force among many Mediterranean and Asian tribes and cultures.
People in Greece also use them in lucky charms, that hang them somewhere in their houses, in order to bring luck to their homes and to decorate the lucky charms of the New Year, called gouria (γούρια).
