Sebastian C. Adams's Synchronological Chart from the late 19th century presents 5,885 years of history (4004 BCE - 1881 AD) on a magnificent 27 inch x 23 foot illustrated and annotated timeline. What a stunner. You can zoom and pan through the whole thing at the David Rumsey Map Collection or order a scaled-down print.
