The stillness of the calm is awful. His voice begins to grow strange and portentous. He feels it in him like something swallowed too big for the esophagus. It keeps up a sort of involuntary interior humming in him, like a live beetle. His cranium is a dome full of reverberations. The hollows of his very bones are as whispering galleries. He is afraid to speak loud, lest he be stunned; like the man in the bass drum.
Herman Melville (1849). “Mardi: And a Voyage Thither”, p.21
