I lingered till the sun went down amongst the trees, and sank crimson and clear behind them. I then turned eastward. On the hill-top above me sat the rising moon; pale yet as a cloud, but brightening momently: she looked over Hay, which, half lost in trees, sent up a blue smoke from its few chimneys; it was yet a mile distant, but in the absolute hush I could hear plainly its thin murmurs of life.
– Charlotte Bronte
Jane Eyre, Chapter 12. During a walk to Hay Jane sits and observes Thornfield and the surrounding countryside, taking in the rising moon. Bronte frequently uses the moon metaphor to symbolize change. In this case it is foreshadowing Jane meeting Mr. Rochester for the first time, although she doesn’t know it is him. This occurs a few minutes later when he falls off his horse on the causeway as “the moon was waxing bright.”
