It follows the entire history of mankind and shows what was happening concurrently around the world with illustrations of many major events, discoveries and prominent people. While maintaining the Victorian design, the chart has been updated and extended so that the time stream continues into the twenty first century, right up to the present day. There are maps and charts, and on the reverse of the timechart there is a vast store of extra information on the different nations' rulers and dynasties.
