Most main pages listed in the Table of Contents have a title graphic across the top of the page. Click on the title graphic to return to the Table of Contents. In some cases clicking on graphics will take you a little further on to more detailed information. Otherwise, clicking on graphics will take you back a step closer to the table of contents, often to one of the main pages. The Codex is an illustrated scroll in which annotations are linked to the pictures. To get out of The Codex, scroll all the way up or down for links. At times you may prefer to use the back and forward buttons on the browser tool bar instead of only using the links provided on a page.
