Let it be thy perpetual meditation, how many physicians who once looked so grim, and so theatrically shrunk their brows upon their patients, are dead and gone themselves. How many astrologers, after that in great ostentation they had foretold the death of some others, how many philosophers after so many elaborate tracts and volumes concerning either mortality or immortality; how many brave captains and commanders, after the death and slaughter of so many; how many kings and tyrants, after they had with such horror and insolency abused their power upon men's lives, as though themselves had been immortal; how many, that I may so speak, whole cities both men and towns: Helice, Pompeii, Herculaneum, and others innumerable are dead and gone. Run them over also, whom thou thyself, one after another, hast known in thy time to drop away.
