Tradition

It's traditional that at this point in the course I post this video.

For those who wish to know more about the flagellants of the middle-ages we mentioned today here's the Google article, the rather interesting Catholic Encyclopedia entry on the flagellants it links to and, above, a demonstration, albeit not from the middle ages, by German rock band Rammstein also courtesy of Google. That's the band beating themselves there and they seem to be really putting some effort into it.
