The following poem is short and rather simple, but requires some background information. If you haven't read the novel (but have perhaps seen TV adaptations or something), or if you want analysis or reason for the poem, read the Post Script (P.S) that follows
The lightning has shattered the tall oak tree
An apt dedication to our unity
Where bolts of hot reality
Cause hopes of untroubled love
To fracture, and so die
As I see, in the shimmering wells of your eyes
Glimmering memories of exotic beauties
That soared through hot eastern skies
I fear your love
Is a deluded feign,
As you scan the red horizons,
In vain
For me to soar through them too
P.S
The poem is a reference to the power struggles in the book as Rochester and Jane enter into their relationship.
In Chapter 24 Rochester makes references to the women he is used to, i.e exotic, alluring, rather promiscuous beauties. Jane consequentially fears that he sees her in the same image and that he is deluding himself into seeing her as an equivalent. Jane is quoted as saying "I will not be your English Celine Varens", i.e that she does not want to live up to the unfairly high expectations he has of her as a wife.
