These flutes, so slender that a breath might almost blow them away, are undoubtedly of the type pictured in many lands in many ages, and known as double flutes—double in the sense of being paired. I have seen such, though of fuller proportions, represented on Egyptian _papyri_ on walls of tombs and temples of the land of the Nile; and on the brass plates of the palaces of Nineveh and Babylon; carved on the frieze of the Parthenon; painted on Etruscan vases, and on the walls of Pompeii and Herculanæum; and far away on the banks of the Petwa (a tributary of the Ganges), sculptured on the gate of Sanchi Tope. And yet through all these instances never have I found any evidence of the means adapted to produce their sounds; anything that would enable one to form a distinct judgment as to the kind of mouthpiece employed in blowing. The number and the positions of the holes have also been involved in doubt. In some few instances holes are to be found marked, but these might be conventionally depicted, and could not be relied upon as guidance to the scale of notes. Then there are the shams and indications put in by the audacity of restorers, so that altogether the learned or academic knowledge concerning the ancient instruments can hardly be said to have emerged from a state of haziness. How welcome, then, must be these Egyptian flutes, which at all events furnish sure evidence of the position of the holes, and of a recognized musical scale determined at a very early date in the development of civilisation. The illustration Fig. 5 gives the relative position of the holes and of the lengths of the flutes, which are shown here one sixth of the actual lengths. [Illustration: _Fig. 5._ _The Gingroi, or flutes of wailing._ _Found in Lady Maket’s Tomb._] All pipes that we call _double flutes_ are represented spreading from the mouth ʌ shaped, held both of them in the mouth, and played one by the right hand and one by the left. All pipes of the ancients the writers were accustomed to call flutes, not discriminating the differences in types, being in fact unaware of the very important distinctions as in later times perceived by specialists in musical lore to be necessary between lip-blown instruments and reed-blown.
