“…partially unveiled the face of Nature, but her immortal lineaments were still a wonder and a mystery.” (pg. 25)
In this passage, Shelley gives nature a gender and physical attributes to something not human. This is an example of personification, a tool used to by authors to make something inanimate more lifelike and expressive. Calling nature a “her” and then using the word lineaments (a word meaning ‘one of the outlines, exterior features, or distinctive marks of a body or figure, particularly of the face’) makes the idea of nature come alive and give Frankenstein more ability to be intimate with the idea of nature.
