A full composite of Adams’ Synchronological Chart of Universal History (1881), which Lovecraft used as a child and which he kept in later life.


Lovecraft called it, in a letter about how he learned as a child, … “a marvellously graphic historic device called “Adams’ Synchronological Chart” — which I still have” (Lord of a Visible World, p.20)

“A huge and impressive twenty-three foot long chart showing 5,885 years of history, from 4004 B.C.. to 1881 A.D. First issued in 1871, Adams put out several editions in many formats.”
