It's also relatively easy to complete, as you only have to read one work dating to before 1600 AD. The challenge dates are between November 2009 and February 28, 2010.
There are some other options, such as the "Classicist" certification:
Personally, I'm not going to attempt "Classicist". At least, not this year.
Optional “Classicist” certification: Become a “classicist” by reading four works written before 1600 A.D. between November 2009 and February 28, 2010.
Extra credit: For a little extra fun, also read a retelling of a classic work. It could be a retelling of the work you read for the first part of the challenge or it could a retelling of any other classic work.
