Johann Christoph Wagner (1640 – c. 1701) was a German theologian, mathematician, and writer active in the 17th century. Wagner was born in Nuremberg where his father, Christoph Wagner, was a cantor at St. Egidien. Wagner studied in Altdorf where he defended works on astrological medicine and the occult properties of abbreviations. Unable to find work in Nuremberg he took to published calendars for astrological work. Around 1680 he relocated to Augsburg where he published, among other things, his well-known descriptions of the orient.
