Even the name, Celt, is not from their own Indo-European language but from Greek. Keltoi, the name given to them by Greek historians, among them Herodotus, means "one who lives in hiding or under cover." The Romans, finding them less mysterious, called them Galli or Gauls, also coming from a Greek word, used by Egyptians as well, hal, meaning "salt." They were the salt people.
