of a musician, perfectly correspond with one another^ 

 and form a full harmony. Aurelius Cassiodorus de- 

 lines symphony to be the art of so adjusting the base 

 to the higher notes, and them to it, through all the 

 voices and instruments, whether they be wind or 

 stringed instruments, that thence an agreeable harmony 

 may result. And Horace speaks expressly of the base 

 and higher tones, and the harmony resulting from 

 their concurrence. All these testimonies therefore 

 uniting in favour of the harmony of the ancients, 

 ought not to leave us the least doubt respecting this 

 branch of their knowledge. We have seen the reason 

 why they did not much use harmony in concert. One 

 fine voice alone, accompanied with one instrument^ 

 regulated entirely by it, pleased them better than 

 mere music without voices, and made a more lively 

 impression on their feeling minds. And this is what 

 even we ourselves every day experience. 



20. I come now to consider the effects, which the 

 ancient music produced, and begin with observing, 

 that it is not at all probable they would unanimously 

 consent to impose upon posterity, in matters delivered 

 with such an air of truth. There is scarcely any 

 thing in history better supported. To begin with 

 sacred story. We find there, that the ministers of 

 Saul bid him send for a player upon an instrument, 

 to relieve him of his malady. The consequence of 

 this was, that David came, and administered the ex. 

 pected relief. And to be convinced, that there was 

 nothing supernatural in this, but that music was at 

 that time a known specific in such maladies as Saul 

 complained ol, it need only be remarked, that those, 

 who gave this advice, were but household servants, 

 Profane history supports us in this reilection,by a great 

 number of instances of the same kind. Aulus Gellius 

 and Athenaeus make mention of many cures performed 

 among the Thebans by music, and cite Theophrastus as 

 towhal happened in his time. Galen,a very graveauthor 

 and whose authority is of the greatest weight in sub-
