Most of Christina Rosetti's poem and art was surrounded around the Oxford Movement. The Oxford Movement is a movement of high members of the Church of England that eventually devloped into Anglo-Catholicism. Their philosophy was known as tractarianism.  Christina joined the oxford movement alolng with her mother and sister in the early 1840s. Her sister became an Angelican nun and that is where she started working with the Angeliccan sisterhood at the Highgate Penitetiary. Which is the inspiration behind the Goblin Market.
