So, this article by Cecil says tennis orginated in France in the 12th or 13th century. This article in Wikipedia says it originated in England in the 19th century. Clearly Wikipedia is wrong, but I’m curious if anyone knows of a source that supports Cecil’s date and country of origin.
I found one pretty reliable cite that backs up Cecil: http://www.straightdope.com/classics/a1_304a.html
Seriously though, I’m no expert but I do know how to use google, and the first hit for “tennis origins” seems to backup Cecil: http://tennis.about.com/od/history/a/earlyhistory.htm
Confusion of terms. Lawn tennis originated in the 19th century. Court tennis, also known as “real tennis”, is medieval.
