"His voice filled the room as the organ fills a great cathedral"

In his book Famous Americans of Recent Times (1867), James Parton agreed that Henry Clay’s chief oratorical asset was his “majestic bass”:

But of all the bodily gifts bestowed by Nature upon this favored child, the most unique and admirable was his voice. Who ever heard one more melodious? There was a depth of tone in it, a volume, a compass, a rich and tender harmony, which invested all he said with majesty. We heard it last when he was an old man past seventy; and all he said was a few words of acknowledgment to a group of ladies in the largest hall in Philadelphia. He spoke only in the ordinary tone of conversation; but his voice filled the room as the organ fills a great cathedral, and the ladies stood spellbound as the swelling cadences rolled about the vast apartment. We have heard much of Whitefield's piercing voice and Patrick Henry's silvery tones, but we cannot believe that either of those natural orators possessed an organ superior to Clay's majestic bass.
