This is currently being exhibited at the Oregon State Library. Sebastian C. Adams was an Oregon pioneer and resident of Salem. He created a twenty-one foot scroll entitled A Chronological Chart of Ancient, Modern, and Biblical History which was a best seller in the 1870's. It presents the history of the world from its Biblical beginnings until the mid 19th century utilizing a richly illustrated timeline.
This scroll is in the tradition of historical timelines popular in the 18th and 19th centuries. Copies can be found in 73 U.S. libraries including those at Yale, Harvard, and Princeton. It was printed in 1871 and then updated and reprinted twice more, in 1876 and 1878.
A photo replica is what is being shown at the Oregon Stat Library along with a second framed copy of a later edition. There's an extensive article in the Salem Statesman Journal .
