It is important to remember that this excellent story is above all a Romantic text, and one in which nature itself is an important force and theme to discuss and consider. We can see therefore, that in Chapter Ten, Victor's emotions to a certain extent are governed by the marvellous natural surroundings that enshroud him. Consider the following description:
These sublime and magnificent scenes afforded me the greatest consolation that I was capable of receiving. They elevated me from all littleness of feeling; and although they did not remove my grief, they subdued and tranquilised it. In some degree, they diverted my mind from the thoughts over which it had brooded for the last month... They congregated around me; the unstained snowy mountain-top, the glittering pinnacle, the ine woods, and ragged bare ravine; the eagle, soaring amidst the clouds--they all gathered round me, and bade me be at peace.
Note the way that Victor's emotions are governed by the beautiful nature that surrounds him. In spite of his massive grief at this point in the novel, nature consoles him and brings him a sense of peace that lulls him to sleep.
In the same way, the feeling of depression and great sadness that Victor wakes up with the next morning is paralleled by nature in a pathetic fallacy. Consider the following description and how it parallels Victor's feelings:
All of soul-inspiring fled with sleep, and dark melancholy clouded every thought. The rain was pouring in torrents, and thick mists hid the summits of the mountains, so that I even saw not the faces of those mighty friends.
Victor's depression is here again exemplified by nature, and the shrouded description of the bad weather perfectly captures the way in which his emotions have become overwhelmed by sadness and grief once again. Therefore key to this chapter is the way in which nature is used to describe Victor's emotions.
