British Library: The Leonardo Notebook

Page through one of Leonardo's notebooks, in which he works out his observations about weights, measures, reflections, and similar material matters. Interesting examples of the master's characteristic "mirror writing" and of his cross-hatched illustrations. Includes written and audio commentary on each spread of pages in the notebook and a magnifying device for looking at details in closeup. Requires Adobe Shockwave player.
