What is Mary Shelly's writing style in Frankenstein?

Considering the structure of the narrative technique which
was used by Mary Shelley in this novel, defining the writing style is rather
complex.

The reasons are due to different factors:first the
multiple and intense influences under which Mary Shelley grew and lived:she was the
daughter of a famous journalist, radical thinker and feminist Mary Wollstonecraft, and
her father, William Godwin, was an important philosopher. Her revolutionary ideas were
probably strengthened by her relationship with Percy Bysshe Shelley, one of the most
outstanding voices of the English Romanticism, whose interests in science - chemistry -
might have represented a further stimulus for Mary. The novel, as a matter of fact,
contains several references to scientific ideas and theories, especially those developed
by Galvani and E. Darwin (electricity and evolutionary principle). Her style is deeply
affected by these influences as the language of some passages may show ( especially when
she describes Victor's fervent study and commitment to his experiments, or when he
attends university lectures of medicine in Ingolstadt).

The
second reason of the complexity of her writing style is caused by the choice of creating
three different narrators: Captain Walton, who writes some letters to her sister to
inform her about his enterprise in finding a new passage into the North Pole, Victor
Frankenstein who comes across Walton's crew while fleeing from his tragic destiny of
death and destruction, finally the monster who tells the story from his own perspective.
Not only this multiple narrating structure overlaps the chronological narration (the
plot is obviously not linear), but it displays a variety of style which are associated
with the main narrators: epistolary form for Walton, highly descriptive, rational, but
intensely emotional in the parts which are told by Victor, tragic, moving and in a way
violent those narrated by the monster. Finally her style is richy in vocabulary, highly
descriptive, especially when she tries to depict the landscape, with its powerful and
threatening aspect, often mirroring the characters' feelings.
