THE ATHENIAN MERCURY, London, June 3, 1693  The back page of this issue has a terrific advertisement for the publication of a book concerning the Salem witch trials, with the ad beginning: "This is to give notice that Mr. Increase and Mr. Cotton Mather's New Discourse concerning the New England WITCHES and WITCHCRAFTS are now arriv'd..." with more, and  ending with: "...Mr. Cotton Mather's First account of the Tryals of the New England Witches, printed on the same size with this last account of Mr. Increase Mather's..." (see photos for the full text). A rare and unique item relating to one of the most notable events in early colonial American history. 
This is the only periodical that we have ever seen with any period reference to the famous witch trials at Salem, Massachusetts. 
A single sheet measuring about 12 1/4 by 7 1/4 inches, never-trimmed margins, and in good condition.
