There is a new book out on images of justice, specifically Lady Justice. You know, Themis, that blindfold, the scales, the sword, the statue. See, e.g., the Wikipedia entry: Scales of Justice.
Visit the Yale Law Library “Justice as a Sign of the Law” exhibit blog post, featuring a book by Yale Law Professors Judith Resnik and Dennis Curtis, “Representing Justice: Invention, Controversy, and Rights in City-States and Democratic Courtrooms,” (New Haven: Yale University Press, 2011).
