It is customary t is customary to regard Mary Shelley's claims to literary distinction as so entirely rooted and grounded in her husband's as to constitute a merely parasitic growth upon his fame. It may be unreservedly admitted that her association with Shelley, and her care of his writings and memory after his death, are the strongest of her titles to remembrance. It is further undeniable that the most original of her works is also that which betrays the strongest traces of his influence. Frankenstein was written when her brain, magnetized by his companionship, was capable of an effort never to be repeated.
