On this day in 1830, Christina Georgina Rossetti was born. She is one of the few women included in the Harvard Classics, and she supposedly was known as much for her beauty as for her poetry (as well as being Dante Rossetti's sister).
It's hard to tell how good a poet she is from the four poems they selected. They mostly dwell on death in an Emily Dickinson-like way.
And yes, Miss Dickinson's work didn't make it into the series. A modern remix of the series would probably swap Christina for Emily without a second thought.
