At this time Byron was about to leave England, pursued, justly or
unjustly, by the hatred of the British mob for a poet who dared to
quarrel with his wife and follow the low manners of some of the
leaders of fashion whom he had been intimate with. Their obscurity has
sheltered _them_ from opprobrium. He was accompanied by the young
physician, Dr. John Polidori, who has somehow passed with Byron's
readers as a fool; yet he certainly could have been no fool in the
ordinary sense of the word, as he had taken full degrees as a doctor
at an earlier age perhaps than had ever been known before. His family,
a simple and highly educated family (his father was Italian, and had
been secretary to Alfieri), caring very much for poetry and
intellectual intercourse, were delighted at the prospect of the young
physician having such an opening to his career, as his sister, the
mother of poets, has told the writer. It is true that this exciting
short period with Byron must have had an injurious effect on the young
physician's after career, though he was still able to obtain the deep
interest of Harriet Martineau at Norwich. It might be added that his
nephew, not only a poet but a leader in poetic thought, deeply
resented the insulting terms in which Byron wrote of Polidori, and,
although h deeply admired the genius of Byron, did not fail to note
where any weakness of form could be found in his work--such is human
nature, and so is poetic justice meted out. This might appear to be a
slight digression from our subject, if it were not for the fact that
when Mary wrote _Frankenstein_ at Secheron, as one of the tales
of horror that were projected by the assembled party, it was only John
Polidori's story of _The Vampire_ which was completed along with
Mary's _Frankenstein_, _The Vampire_, published anonymously,
was at first extolled everywhere under the idea that it was Byron's,
and when this idea was found to be a mistake the tale was slighted in
