Minor Characters
The Oak-tree
The Oak-tree is both a friend of the Nightingale and the place where she makes her home. Like the Rose-tree, the Oak-tree understands the seriousness of the Nightingale's intended sacrifice, and he begs her to sing one last song for him before she goes to her death.
The Professor
Although he never appears in the story, the Professor is a symbolically important character. Like the Student, the Professor has clear ties to academia and intellectualism. Interestingly, however, he is also the father of the girl, suggesting a link between the Student's "rational" worldview and the girl's materialism.
The White Rose-tree
This is the first tree the Nightingale visits on her search for a red rose. He does not have one, so he sends her to his brother, the Yellow Rose-tree.
The Yellow Rose-tree
This is the second tree the Nightingale visits on her search for a red rose. He does not have one, so he sends her to his brother, the Red Rose-tree.
