seated close by. On the Greek monuments of the pre-Roman period we always find two similar flutes connected together, but afterwards, and especially in pictures connected with the worship of Cybele, one of the flutes very often has a curved horn, which seems to have been a special peculiarity of the Phrygian flute. This was apparently not known to the Greeks in ancient times. [Illustration: FIG. 142.] The other wooden wind instruments are of no special importance for music or art. The _Syrinx_, or pan-pipe, constructed of a number of reeds fastened together, which in one kind of syrinx were all of equal length, but in others varied from short to long, was used by the shepherds, and is often seen in pictures, especially of Pan and other forest and field divinities, but played no part in actual music. Still more is this the case with the _Plagiaulos_, answering to the modern _Flûte traversière_, which originated in Egypt, and with various other kinds of single flutes which have been described to us. Metal wind instruments, or trumpets (σάλπυγξ), were only used for military and religious purposes. They were usually made of bronze, with a bone mouthpiece, were of a longish shape, with a very broad mouth. Among other musical instruments in use among the Greeks we must mention tambourines (τύμπανα), cymbals, and castanets (κρόταλα), which were used in the worship of Dionysus and Cybele, and in dances of an orgiastic character; in Fig. 142 a girl, dancing to the sound of a flute, holds castanets in her hands. But, in spite of the frequency with which these instruments are represented on works of art, especially those which are connected with Dionysus, their use in daily life must have been very rare, except for the dancing girls who appeared at the symposia, and who marked the time of their motions with them.
