Doing a bit of research I came across the online version (g) of the Bambergische Peinliche Halsgerichtsordnung, one of the first European criminal codes. It was written by a German knight, one Johann the Strong, Baron of Schwarzenberg and Hohenlandsberg. Johann was 'Hofmeister' (a senior court official) to the Bishop of Bamberg.
From a legal perspective the Bamberg code is forward-looking in many ways, but in other ways it's, er, medieval. And what's even more awesome is that the medieval stuff is illustrated. Directly below we see court officials preparing for interrogation under torture, the so-called peinliche Befragung (g). It's even accompanied by a short poem (anyone want to try a translation in comments?). Below that we see a man about to be beheaded with a sword in the foreground, with a poor bastard broken on the wheel in the background.
