Moderator Note: Please note that this is an old thread, started in Aug 2009, and the post prior to augi_01’s is from Oct 2010. That’s not a problem, augi_01, I just don’t want people to think that the prior posters will necessarily respond – they may not be around these boards any more, they may have forgot what they posted, etc. Anyhow, welcome to the Straight Dope Message Boards!
Those are outside the time period of consideration, the late 1400s and early 1500s. Supposedly there was a “rule” that “America” violated, so we’re looking for cites that jusitfy the existance of that rule. Places named 2 centuries later don’t really matter.
