Hmm... old French... is that very different from modern French? I'd like to know because in German, it's VERY different. In English, well... kind of. But in Spanish, it's really similar. If you can read Spanish, you can read many medieval texts because it has not changed very much. Of course, the vocabulary tends to be a bit problematic... *cough*
Btw, ins't it fascinating to see how threads trail off-topic and eventually develop into a discussion about something totally different?
