Christina Rosetti is best remembered as a devotional or religious poet, something that would ordinarily condemn her to a minor status. It is entirely unfair, of course, since Hopkins could have a blazing career in the same genre of writing. Being a man in the 19th Century made his far more likely, for women struggled to be heard or taken seriously.

Rosetti's brother, Dante Gabriel Rosetti (yes, the very same who gained fame as a poet and artist in the Pre-Raphaelite Brotherhood) thought her verse the best since Elizabeth Barret Browning. He meant women's verse, of course. In any event, she is highly regarded today and underwent a kind of renaissance late last century.

I have a volume of her poetry on my kindle and have been reading a few poems very night. It's true that if you are not of a religious persuasion. then you might find her subject matter a stumbling block. For me, it is all joy. 

from Uphill

Does the road wind uphill all the way?

Yes, to the very end,

Will the day's journey take the whole long day?

From morn to night, my friend.

from The One Certainty 

Vanity of vanities, the Preacher saith,

All things are vanity. The eye and ear

Cannot be filled with what they see and hear,

Like early dew or like the sudden breath

Of wind, or like the grass that withereth,

Is man tossed to and fro by hope and fear,

So little joy hath he, so little cheer....
