Mary Shelley's short stories

July 16, 1833.--This is a memorable anniversary for me; on it I complete my three hundred and twenty-third year!
The Wandering Jew?--certainly not. More than eighteen centuries have passed over his head. In comparison with him, I am a very young Immortal.
Am I, then, immortal? This is a question which I have asked myself, by day and night, for now three hundred and three years, and yet cannot answer it. I detected a grey hair amidst my brown locks this very day--that surely signifies decay. Yet it may have remained concealed there for three hundred years--for some persons have become entirely white-headed before twenty years of age.
I will tell my story, and my reader shall judge for me. I will tell my story, and so contrive to pass some few hours of a long eternity, become so wearisome to me. For ever! Can it be? to live for ever! I have heard of enchantments, in which the victims were plunged into a deep sleep, to wake, after a hundred years, as fresh as ever: I have heard of the Seven Sleepers--thus to be immortal would not be so burthensome: but, oh! the weight of never-ending time--the tedious passage of the still-succeeding hours! How happy was the fabled Nourjahad!--But to my task.
