A great documentary series on Rome

I'm currently working through Mary Beard's book, 'SPQR - A history of Ancient Rome'.  It' a good book and worth reading if you are interested in Roman history like I am.

In the last day or so, I stumbled upon a documentary series developed by Mary on Rome. I'm currently two episodes in, and have already learned so many fascinating things I didn't know previously.

There are four episodes in the series.  They can be found here, but you may be able to find them on youtube.

What documentaries have you watched lately?
