Adams Synchronological Chart or Map of History, originally published as Chronological Chart of Ancient, Modern and Biblical History is a synchronological wallchart and timeline ("timechart") that graphically depicts the history of mankind from 4000 BC, the biblical beginning of man, to modern times. The chart is based on the Bible, thus a chronological history of the Bible is presented on its first pages, causing nowadays some reluctance to use the chart, that eventually merges with secular history on the pages following.
