On the event side, each centimetre represents ten years of world history. It recalls significant data from the Roman times until the Millennium, from Jesus Christ to the Internet. The periods side presents world history divided into its fundamental periods. Entries on intellect, powers, and the arts on a backdrop ranging from LATE ANTIQUITY until the MODERN TIMES provide a context for individual events. For convenience, an inch scale has been added! The wooden ruler made in Germany is a big success in bookshops and museum stores worldwide.
