Answer: The Maid lived in a rural setting.
Step-by-step explanation:
The poem is about a maid called Lucy who was very beautiful whilst she was alive. Her beauty was not acknowledged or praised by people however, because she was in a lonely area.
The adjective, "untrodden" is meant to symbolize that she stayed in a rural setting such as a village or countryside because these places do not see a lot of people coming to them which means that they do not get the chance to step/ tread on these areas.
