Describe Nicholas's bed-chamber and his lodgings. Why stuff does he keep there? How does this suggest two aspects of his identity?

Most of Nicholas' items are the items of a student: his textbooks, his astrolabe, and other tools of his learning. He also kept his room very neat and clean; he kept herbs so it smelled pleasant. He could make beautiful music with his psaltery; he had little, but lived with what he had and what his friends provided. Most of his music was made at night.
