The Mycenaean Tablet: From the people who found it
Actually, it's Pylian, but I didn't think that would get people's attention. Here is an article from the UT website with an account from Cynthia Shelmerdine about the finding of the tablet, which is now described as the oldest readable writing from antiquity. (It says the number 1 and somebody's name; the back side says that something is "finished." Maybe.) She was my first-year Greek teacher, and she started the class off by explaining how to write Linear B.
