Centuries Reading Challenge

This one is interesting: The Centuries Challenge, hosted by Becky's Book Reviews.

From the Challenge Page:

Your challenge--if you choose to accept it--is to read four (to six) books from four different centuries [written in different centuries]. (If you choose to read six books altogether, then you can double up on centuries if you like. You can always read more than six. But you're not obligated to in any way.)

 My list (when I decide):

1.
