Here then, in Zuni, we have the bull-roarer again, and once more we find it employed as a summons to the mysteries. We do not learn, however, that women in Zuni are forbidden to look upon the bull-roarer. Finally, the South African evidence, which is supplied by letters from a correspondent of Mr. Tylor's, proves that in South Africa, too, the bull-roarer is employed to call the men to the celebration of secret functions. A minute description of the instrument, and of its magical power to raise a wind, is given in Theal's _Kaffir Folklore_, p. 209. The bull-roarer has not been made a subject of particular research; very probably later investigations will find it in other parts of the modern world besides America, Africa, New Zealand, and Australia. I have myself been fortunate enough to encounter the bull-roarer on the soil of ancient Greece and in connection with the Dionysiac mysteries. Clemens of Alexandria, and Arnobius, an early Christian father who follows Clemens, describe certain toys of the child Dionysus which were used in the mysteries. Among these are _turbines_, κῶνοι and ῥόμβοι. The ordinary dictionaries interpret all these as whipping-tops, adding that ῥόμβος is sometimes 'a magic wheel.' The ancient scholiast on Clemens, however, writes: 'The κῶνος is a little piece of wood, to which a string is fastened, and in the mysteries it is whirled round to make a roaring noise.'[23] Here, in short, we have a brief but complete description of the bull-roarer of the Australian _turndun_. No single point is omitted. The κῶνος, like the _turndun_, is a small object of wood, it is tied to a string, when whirled round it produces a roaring noise, and it is used at initiations. This is not the end of the matter.
