Muta Persona

Abraham Cowley, "Of Obscurity", The Essays of Abraham Cowley (New York: Scribner, Welford & Co., 1869), pp. 35-6:

I account a person who has a moderate mind and fortune, and lives in the conversation of two or three agreeable friends, with little commerce in the world besides; who is esteemed well enough by his few neighbours that know him, and is truly irreproachable by anybody; and so after a healthful quiet life, before the great inconveniences of old age, goes more silently out of it than he came in (for I would not have him so much as cry in the exit); this innocent deceiver of the word, as Horace calls him, this muta persona, I take to have been more happy in his part, than the greatest actors that fill the stage with show and noise, nay, even than Augustus himself, who asked with his last breath, whether he had not played his farce very well.
