At a distance, his portraits looked like normal human portraits. However, individual objects in each portrait were actually overlapped together to make various anatomical shapes of a human. They were carefully constructed by his imagination. The assembled objects in each portrait were not random: each was related by characterization. In the portrait now represented by several copies called The Librarian, Arcimboldo used objects that signified the book culture at that time, such as the curtain that created individual study rooms in a library. The animal tails, which became the beard of the portrait, were used as dusters. By using everyday objects, the portraits were decoration and still-life paintings at the same time. His works showed not only nature and human beings, but also how closely they were related.
